  • An Improved SPSIM Index for Image Quality Assessment
    S S symmetry Article An Improved SPSIM Index for Image Quality Assessment Mariusz Frackiewicz * , Grzegorz Szolc and Henryk Palus Department of Data Science and Engineering, Silesian University of Technology, Akademicka 16, 44-100 Gliwice, Poland; [email protected] (G.S.); [email protected] (H.P.) * Correspondence: [email protected]; Tel.: +48-32-2371066 Abstract: Objective image quality assessment (IQA) measures are playing an increasingly important role in the evaluation of digital image quality. New IQA indices are expected to be strongly correlated with subjective observer evaluations expressed by Mean Opinion Score (MOS) or Difference Mean Opinion Score (DMOS). One such recently proposed index is the SuperPixel-based SIMilarity (SPSIM) index, which uses superpixel patches instead of a rectangular pixel grid. The authors of this paper have proposed three modifications to the SPSIM index. For this purpose, the color space used by SPSIM was changed and the way SPSIM determines similarity maps was modified using methods derived from an algorithm for computing the Mean Deviation Similarity Index (MDSI). The third modification was a combination of the first two. These three new quality indices were used in the assessment process. The experimental results obtained for many color images from five image databases demonstrated the advantages of the proposed SPSIM modifications.

  • SAF7115 Multistandard Video Decoder with Super-Adaptive Comb Filter
    SAF7115 Multistandard video decoder with super-adaptive comb filter, scaler and VBI data read-back via I2C-bus Rev. 01 — 15 October 2008 Product data sheet 1. General description The SAF7115 is a video capture device that, due to its improved comb filter performance and 10-bit video output capabilities, is suitable for various applications such as In-car video reception, In-car entertainment or In-car navigation. The SAF7115 is a combination of a two channel analog preprocessing circuit and a high performance scaler. The two channel analog preprocessing circuit includes source-selection, an anti-aliasing filter and Analog-to-Digital Converter (ADC) per channel, an automatic clamp and gain control, two Clock Generation Circuits (CGC1 and CGC2) and a digital multi standard decoder that contains two-dimensional chrominance/luminance separation utilizing an improved adaptive comb filter. The high performance scaler has variable horizontal and vertical up and down scaling and a brightness/contrast/saturation control circuit. The decoder is based on the principle of line-locked clock decoding and is able to decode the color of PAL, SECAM and NTSC signals into ITU-601 compatible color component values. The SAF7115 accepts CVBS or S-video (Y/C) from TV or VCR sources as analog inputs, including weak and distorted signals. The expansion port (X-port) for digital video (bi-directional half duplex, D1 compatible) can be used to either output unscaled video using 10-bit or 8-bit dithered resolution or to connect to other external digital video sources for reuse of the SAF7115 scaler features. The enhanced image port (I-port) of the SAF7115 supports 8-bit and 16-bit wide output data with auxiliary reference data for interfacing, e.g.

  • Color Image Enhancement with Saturation Adjustment Method

This approach makes the color over-saturate very easily and makes the image look unnatural. In this study, we try to use the concept of exposure compensation to simulate the brightness changes and to find the relationship among luminance, saturation, and hue. The simulation indicates that saturation changes withthe change of luminance and the simulation also shows there are certain relationships between color variation model and YCbCr color model. Together with all these symptoms, we also include the human vision characteristics to propose a new saturation method to enhance the vision effect of an image. As results, the proposed approach can make the image have better vivid and contrast. Most important of all, unlike the over-saturation caused by the conventional approach, our approach prevents over-saturation and further makes the adjusted image look natural.

    ColorNet: Investigating the importance of color spaces for image classification⋆ Shreyank N Gowda1 and Chun Yuan2 1 Computer Science Department, Tsinghua University, Beijing 10084, China [email protected] 2 Graduate School at Shenzhen, Tsinghua University, Shenzhen 518055, China [email protected] Abstract. Image classification is a fundamental application in computer vision. Recently, deeper networks and highly connected networks have shown state of the art performance for image classification tasks. Most datasets these days consist of a finite number of color images. These color images are taken as input in the form of RGB images and clas- sification is done without modifying them. We explore the importance of color spaces and show that color spaces (essentially transformations of original RGB images) can significantly affect classification accuracy. Further, we show that certain classes of images are better represented in particular color spaces and for a dataset with a highly varying number of classes such as CIFAR and Imagenet, using a model that considers multi- ple color spaces within the same model gives excellent levels of accuracy. Also, we show that such a model, where the input is preprocessed into multiple color spaces simultaneously, needs far fewer parameters to ob- tain high accuracy for classification. For example, our model with 1.75M parameters significantly outperforms DenseNet 100-12 that has 12M pa- rameters and gives results comparable to Densenet-BC-190-40 that has 25.6M parameters for classification of four competitive image classifica- tion datasets namely: CIFAR-10, CIFAR-100, SVHN and Imagenet. Our model essentially takes an RGB image as input, simultaneously converts the image into 7 different color spaces and uses these as inputs to individ- ual densenets.

  • Ycbcr 10-Bit to RGB565 Converter
    YCbCr 10-Bit to RGB565 Converter April 2013 Reference Design RD1151 Introduction YCbCr 10-bit to RGB565 converter converts YCbCr 4:2:2 10-bit color space information to RGB565 color space. To facilitate easy insertion to practical video systems, the design example takes up to three video stream control sig- nals (H_SYNC, V_SYNC, FID, and DEN) and delays them appropriately, so that control signals can be easily syn- chronized with the output video stream. This document provides a brief description of YCbCr 10-bit to RGB565 Converter and its implementation. The design is implemented in VHDL. The Lattice iCEcube2™ Place and Route tool integrated with the Synopsys Synplify Pro® synthesis tool is used for the implementation of the design. The design can be targeted to other iCE40™ FPGA product family devices. Features • 10-bit YCbCr 4:2:2 input and RGB565 output • Pipelined implementation • Latency of 4 cycles • H_SYNC, V_SYNC, FID and DEN control signals for video synchronization • VHDL RTL and functional test bench Functional Description Figure 1.
