Perceptually Motivated Image Features Using Contours

Abstract: Abstract-Dong et al. examined the ability of 51 computational feature sets to estimate human perceptual texture similarity, however, none performed well for this task. While it is well-known that the human visual system is extremely adept at exploiting longer-range aperiodic (and periodic) "contour" characteristics in images, none of the investigated feature sets exploit higher order statistics (HOS) over larger image regions (>19×19 pixels). We therefore hypothesise that long-range HOS, in the form of contour… Show more

“…However, these elements often contain more than one segment and thereby cannot be used to represent the shape of a single contour. Compared with the PMIF descriptor [18] based on contours, this paper addresses its open issues by representing local contour segments in a more powerful way via conton learning, and modelling the global spatial layout of words in longer ranges.…”

“…Inspired by the importance of contour cues to human visual perception of imagery [15], [18], [23], [51], [68], we introduce a global image descriptor (see Fig. 1 for pipeline) which exploits the spatial layout of words (SLoW) based on contours.…”

“…The area of Content Based Image Retrieval has given a note worthy stride in the area of image retrievals and the main advantage with this mechanism is that based on content effective retrievals from massive datasets are made possible. This content can be either the visual features ,textual features, shape features or any other feature that helps in proper identification of image under studying and thereby helping towards efficient retrievals [1] [2][3][4] [5].With this features many applications have been developed and are being utilized in real time situations including the domains of health care, medical, E-business, etc., [6] [7] [8]. Many models are thus subjected to using both parametric model based approaches and non parametric model based approaches.…”
