Features and the ‘primal sketch’
This review is concerned primarily with psychophysical and physiological evidence relevant to the question of the existence of spatial features or spatial primitives in human vision. The review will be almost exclusively confined to features defined in the luminance domain. The emphasis will be on the experimental and computational methods that have been used for revealing features, rather than...
متن کاملReading Report: Video Primal Sketch
In this report, we discuss a content-based video coding approach, i.e. video primal sketch. Unlike traditional video coding approaches, video primal sketch seeks to capture different mid-level cues and use them to explain the video data. The algorithm first segmented the video data into two different kinds of regions: explicit region and implicit region, and then model each region by a correspo...
متن کاملPrimal sketch : Integrating structure and texture q
This article proposes a generative image model, which is called ‘‘primal sketch,’’ following Marr’s insight and terminology. This model combines two prominent classes of generative models, namely, sparse coding model and Markov random field model, for representing geometric structures and stochastic textures, respectively. Specifically, the image lattice is divided into structure domain and tex...

متن کاملPrimal Sketch: Integrating Texture and Structure
Following Marr’s insight, we propose a generative image representation called primal sketch, which integrates two modeling components. The first component explains the structural part of an image, such as object boundaries, by a hidden layer of image primitives. The second component models the remaining textural part without distinguishable elements by Markov random fields that interpolate the ...
