  • Read and Write Images from a Database Using SQL Server
    HOWTO: Read and write images from a database using SQL Server Atalasoft is an imaging SDK and we do not directly have any dependencies on, or specific functionality for Database access (with the single exception of our DbImageSource class). However, since the typical means of image storage in a database is a BLOB (Binary Long Object), developers can take advantage of the AtalaImage.ToByteArray and AtalaImage.FromByteArray methods to use in their own code to store and retrieve image data to and from databases respectively. Atalasoft dotImage has streaming capabilities that can be used jointly with ADO.NET to read and write images directly to a database without saving to a temporary file. The following code snippets demonstrates this in C# and VB.NET. Please note that the code examples below are provided as a courtesy/convenience only and are not meant to be production code or represent the only way to access a database. The code is provided as is as but an example of how to get the needed data in a byte array suitable for use in storing to a database and how to take binary data containing an image back into an AtalaImage to use in our SDK. Write to a Database C# rivate void SaveToSqlDatabase(AtalaImage image) { SqlConnection myConnection = null; try { // Save image to byte array. // we will be storing this image as a Jpeg using our JpegEncoder with 75 quality // you could use any of our ImageEncoder classes to store as the respective image types byte[] imagedata = image.ToByteArray(new Atalasoft.Imaging.Codec.JpegEncoder(75)); // Create the SQL statement to add the image data.

  • Eloquence: HP 3000 IMAGE Migration by Michael Marxmeier, Marxmeier Software AG
    Eloquence: HP 3000 IMAGE Migration By Michael Marxmeier, Marxmeier Software AG Michael Marxmeier is the founder and President of Marxmeier Software AG (www.marxmeier.com), as well as a fine C programmer. He created Eloquence in 1989 as a migration solution to move HP250/HP260 applications to HP-UX. Michael sold the package to Hewlett-Packard, but has always been responsible for Eloquence development and support. The Eloquence product was transferred back to Marxmeier Software AG in 2002. This chapter is excerpted from a tutorial that Michael wrote for HPWorld 2003. Email: [email protected] Eloquence is a TurboIMAGE compatible database that runs on HP-UX, Linux and Windows.Eloquence supports all the TurboIMAGE intrinsics, almost all modes, and they behave identically. HP 3000 applications can usually be ported with no or only minor changes. Compatibility goes beyond intrinsic calls (and also includes a performance profile.) Applications are built on assumptions and take advantage of specific behavior. If those assumptions are no longer true, the application may still work, but no longer be useful. For example, an IMAGE application can reasonably expect that a DBFIND or DBGET execute fast, independently of the chain length and that DBGET performance does not differ substantially between modes. If this is no longer true, the application may need to be rewritten, even though all intrinsic calls are available. Applications may also depend on external utilities or third party tools. If your application relies on a specific tool (let’s say, Robelle’s SUPRTOOL), you want it available (Suprtool already works with Eloquence). If a tool is not available, significant changes to the application would be required.

  • Oracle Multimedia Image PL/SQL API Quick Start
    Oracle Multimedia Image PL/SQL API Quick Start Introduction Oracle Multimedia is a feature that enables Oracle Database to store, manage, and retrieve images, audio, video, and other heterogeneous media data in an integrated fashion with other enterprise information. Oracle Multimedia extends Oracle Database reliability, availability, and data management to multimedia content in media-rich applications. This article provides simple PL/SQL examples that upload, store, manipulate, and export image data inside a database using Oracle Multimedia’s PL/SQL packages. Some common pitfalls are also highlighted. The PL/SQL package used here is available in Oracle Database release 12c Release 2 or later with Oracle Multimedia installed (the default configuration provided by Oracle Universal Installer). The functionality in this PL/SQL package is the same as the functionality available with the Oracle Multimedia relational interface and object interface. For more details refer to Oracle Multimedia Reference and Oracle Multimedia User’s Guide. The following examples will show how to store images within the database in BLOB columns so that the image data is stored in database tablespaces. Oracle Multimedia image also supports BFILEs (pointers to files that reside on the filesystem), but this article will not demonstrate the use of BFILEs. Note that BFILEs are read -only so they can only be used as the source for image processing operations (i.e. you can process from a BFILE but you can’t process into a BFILE). NOTE: Access to an administrative account is required in order to grant the necessary file system privileges. In the following examples, you should change the command connect sys as sysdba to the appropriate one for your system: connect sys as sysdba Enter password: password The following examples also connect to the database using connect ron Enter password: password which you should change to an actual user name and password on your system.

  • A 10 Million Image Database for Scene Recognition
    This article has been accepted for publication in a future issue of this journal, but has not been fully edited. Content may change prior to final publication. Citation information: DOI 10.1109/TPAMI.2017.2723009, IEEE Transactions on Pattern Analysis and Machine Intelligence 1 Places: A 10 million Image Database for Scene Recognition Bolei Zhou, Agata Lapedriza, Aditya Khosla, Aude Oliva, and Antonio Torralba Abstract—The rise of multi-million-item dataset initiatives has enabled data-hungry machine learning algorithms to reach near- human semantic classification performance at tasks such as visual object and scene recognition. Here we describe the Places Database, a repository of 10 million scene photographs, labeled with scene semantic categories, comprising a large and diverse list of the types of environments encountered in the world. Using the state-of-the-art Convolutional Neural Networks (CNNs), we provide scene classification CNNs (Places-CNNs) as baselines, that significantly outperform the previous approaches. Visualization of the CNNs trained on Places shows that object detectors emerge as an intermediate representation of scene classification. With its high-coverage and high-diversity of exemplars, the Places Database along with the Places-CNNs offer a novel resource to guide future progress on scene recognition problems. Index Terms—Scene classification, visual recognition, deep learning, deep feature, image dataset. F 1 INTRODUCTION Whereas most datasets have focused on object categories If a current state-of-the-art visual recognition system would (providing labels, bounding boxes or segmentations), here send you a text to describe what it sees, the text might read we describe the Places database, a quasi-exhaustive repos- something like: “There is a sofa facing a TV set.

  • Using Free Pascal to Create Android Applications
    Using Free Pascal to create Android applications Michaël Van Canneyt January 19, 2015 Abstract Since several years, Free pascal can be used to create Android applications. There are a number of ways to do this, each with it’s advantages and disadvantages. In this article, one of the ways to program for Android is explored. 1 Introduction Programming for Android using Free Pascal and Lazarus has been possible since many years, long before Delphi unveiled its Android module. However, it is not as simple a process as creating a traditional Desktop application, and to complicate matters, there are several ways to do it: 1. Using the Android NDK. Google makes the NDK available for tasks that are CPU- intensive (a typical example are opengl apps), but warns that this should not be the standard way of developing Android apps. This is the way Delphi made it’s Android port: Using Firemonkey – which uses OpenGL to draw controls – this is the easiest approach. There is a Lazarus project that aims to do things in a similar manner (using the native-drawn widget set approach). 2. Using the Android SDK: a Java SDK. This is the Google recommended way to create Android applications. This article shows how to create an Android application using the Java SDK. 2 FPC : A Java bytecode compiler The Android SDK is a Java SDK: Android applications are usually written in Java. How- ever, the Free Pascal compiler can compile a pascal program to Java Bytecode. This is done with the help of the JVM cross-compiler. Free Pascal does not distribute this cross-compiler by default (yet), so it must be built from sources.

  • Decision Support and Data Warehousing in an HP 3000 Environment
    Paper# : 3011 Decision Support and Data Warehousing in an HP 3000 Environment. Christophe Jacquet Hewlett-Packard Co. 19447 Pruneridge Ave Cupertino, CA, 94087 Email: [email protected] Decision Support and Data Warehousing in an HP 3000 Environment. 3011 - 1 As corporate downsizing continues, flatter organizational structures give end users more decision making responsibilities. HP 3000 users can take advantage of powerful tools such as Image/SQL and ODBC drivers to gain direct access to the data in the databases. While these tools provide real benefits, the limitations of directly accessing operational data, in terms of performance, concurrency, ease of use and data quality, are rapidly becoming apparent. A current approach to Decision Support is the consolidation of company-wide data into a separately designed environment, commonly called a Data Warehouse. This paper covers the benefits and history of Data Warehouses and examines a variety of approaches available within the HP 3000 marketplace to implement such a Decision Support environment. It describes the elements needed to create a Data Warehouse environment from the Decision Support data store to the end user desktop, including extraction and cleansing tools. Data Warehousing is just one example of how enhancements to the MPE/iX operating environment permit HP 3000 customers to take full advantage of the many new technologies and approaches emerging in the Information Technology marketplace. Why is decision support important. In today’s world, companies have to be able to make decisions much faster than before. Making the right decisions at the right time can provide significant competitive advantage for a company.
