Depth-Aware Blending of Smoothed Images for Bokeh Effect Generation
1 Depth-aware Blending of Smoothed Images for Bokeh Effect Generation Saikat Duttaa,∗∗ aIndian Institute of Technology Madras, Chennai, PIN-600036, India ABSTRACT Bokeh effect is used in photography to capture images where the closer objects look sharp and every- thing else stays out-of-focus. Bokeh photos are generally captured using Single Lens Reflex cameras using shallow depth-of-field. Most of the modern smartphones can take bokeh images by leveraging dual rear cameras or a good auto-focus hardware. However, for smartphones with single-rear camera without a good auto-focus hardware, we have to rely on software to generate bokeh images. This kind of system is also useful to generate bokeh effect in already captured images. In this paper, an end-to-end deep learning framework is proposed to generate high-quality bokeh effect from images. The original image and different versions of smoothed images are blended to generate Bokeh effect with the help of a monocular depth estimation network. The proposed approach is compared against a saliency detection based baseline and a number of approaches proposed in AIM 2019 Challenge on Bokeh Effect Synthesis. Extensive experiments are shown in order to understand different parts of the proposed algorithm. The network is lightweight and can process an HD image in 0.03 seconds. This approach ranked second in AIM 2019 Bokeh effect challenge-Perceptual Track. 1. Introduction tant problem in Computer Vision and has gained attention re- cently.

The General Idea Behind Editing in Narrative Film Is the Coordination of One Shot with Another in Order to Create a Coherent, Artistically Pleasing, Meaningful Whole
Chapter 4: Editing Film 125: The Textbook © Lynne Lerych The general idea behind editing in narrative film is the coordination of one shot with another in order to create a coherent, artistically pleasing, meaningful whole. The system of editing employed in narrative film is called continuity editing – its purpose is to create and provide efficient, functional transitions. Sounds simple enough, right?1 Yeah, no. It’s not really that simple. These three desired qualities of narrative film editing – coherence, artistry, and meaning – are not easy to achieve, especially when you consider what the film editor begins with. The typical shooting phase of a typical two-hour narrative feature film lasts about eight weeks. During that time, the cinematography team may record anywhere from 20 or 30 hours of film on the relatively low end – up to the 240 hours of film that James Cameron and his cinematographer, Russell Carpenter, shot for Titanic – which eventually weighed in at 3 hours and 14 minutes by the time it reached theatres. Most filmmakers will shoot somewhere in between these extremes. No matter how you look at it, though, the editor knows from the outset that in all likelihood less than ten percent of the film shot will make its way into the final product. As if the sheer weight of the available footage weren’t enough, there is the reality that most scenes in feature films are shot out of sequence – in other words, they are typically shot in neither the chronological order of the story nor the temporal order of the film. -

Portraits in particular have become reconfigured into what Mark B. Hansen has called “digital facial images” and Mitra Azar has subsequently reworked into “algorithmic facial images.” 1 This transition has amplified the role of portraiture as a representational device, as a node in a network -

As media moves full steam ahead into the digital revolution and beyond, it is a natural instinct to look back at where we?ve come from. With more artists rediscovering photography?s historical processes, the practice of photography continually redefines and re-contextualizes itself. The creative possibilities of these historical processes are endless, spawning a growing arena of practice - alternative processes, which combines past, present and everything in between, in the creation of art. This collection is an introduction to and a sample of these processes and possibilities. With Alternative Photographic Processes, Brady Wilks demonstrates techniques for manipulating photographs, negatives and prints ? emphasizing the ?hand-made? touch. Bridging the gap between the simplest of processes to the most complex, Wilks? introduction demonstrates image-manipulation pre-capture, allowing the artist to get intimate with his or her images long before development.

Before Zen: the Nothing of American Dada
Before Zen The Nothing of American Dada Jacquelynn Baas One of the challenges confronting our modern era has been how to re- solve the subject-object dichotomy proposed by Descartes and refined by Newton—the belief that reality consists of matter and motion, and that all questions can be answered by means of the scientific method of objective observation and measurement. This egocentric perspective has been cast into doubt by evidence from quantum mechanics that matter and motion are interdependent forms of energy and that the observer is always in an experiential relationship with the observed.1 To understand ourselves as in- terconnected beings who experience time and space rather than being sub- ject to them takes a radical shift of perspective, and artists have been at the leading edge of this exploration. From Marcel Duchamp and Dada to John Cage and Fluxus, to William T. Wiley and his West Coast colleagues, to the recent international explosion of participatory artwork, artists have been trying to get us to change how we see. Nor should it be surprising that in our global era Asian perspectives regarding the nature of reality have been a crucial factor in effecting this shift.2 The 2009 Guggenheim exhibition The Third Mind emphasized the im- portance of Asian philosophical and spiritual texts in the development of American modernism.3 Zen Buddhism especially was of great interest to artists and writers in the United States following World War II. The histo- ries of modernism traced by the exhibition reflected the well-documented influence of Zen, but did not include another, earlier link—that of Daoism and American Dada. -

STAY SAFE AND OBSERVE SET ETIQUETTE POST-PRODUCTION (2 guides) EXHIBITION AND DISTRIBUTION (2 guides) PRODUCTION MASTER THE CAMERA Master the camera (camera shots, angles and movements) Top Tip Before you begin making your film, have a play with your camera: try to film something! A simple, silent (no dialogue) scene where somebody walks into the shot, does something and then leaves is perfect. Once you’ve shot your first film, watch it. What do you like/dislike about it? Save this first attempt. We’ll be asking you to return to it later. (If you have already done this and saved your films, you don’t need to do this again.) Professional filmmakers divide scenes into shots. They set up their camera and frame the first shot, film the action and then stop recording. This process is repeated for each new shot until the scene is completed. The clips are then put together in the edit to make one continuous scene. Whatever equipment you work with, if you use professional techniques, you can produce quality films that look cinematic. The table below gives a description of the main shots, angles and movements used by professional filmmakers. An explanation of the effects they create and the information they can give the audience is also included.
