Shapes in images provide important features for pattern recognition, pattern matching, content-based image retrieval, etc. In this paper, a contour based structural approach is proposed to represent any arbitrary shape in an image by an alpha-numeric string. The proposed method performs decomposition of the region into disjoint sub-regions by detecting the(More)
ColorFingers is a WYSIWYG, Location Independent Touch (LIT) based color picking tool aimed to give unique and swift interaction in choosing color on touch based devices. It makes use of touch interface and the touch information of two fingers to select almost 16 million colors. This tool is a model to prove how touch can be interpreted in different ways to(More)
To define and identify a region-of-interest (ROI) in a digital image, the shape descriptor of the ROI has to be described in terms of its boundary characteristics. To address the generic issues of contour tracking, the yConvex Hypergraph (yCHG) model was proposed by Kanna et al [1]. This yCHG model represents any connected region as a finite set of disjoint(More)
