The richness of natural images makes the quest for optimal representations in image
processing and computer vision challenging. The latter observation has not prevented the …

Intelligent video coding (IVC), which dates back to the late 1980s with the concept of
encoding videos with knowledge and semantics, includes visual content compact …

This paper proposes a novel image compression scheme based on the local feature
descriptor-Scale Invariant Feature Transform (SIFT). The SIFT descriptor characterizes an …

A new method for segmenting intensity images into smooth surface segments is presented.
The main idea is to divide the image into flat, planar, convex, concave, and saddle patches …

Image sparse representation methods have been widely applied in many image processing
fields, such as computer vision, image de-noising, super resolution, and visual tracking. An …

In this paper a special class of functions called smoothlets is presented. They are defined as
a generalization of wedgelets and second-order wedgelets. Unlike all known geometrical …

Colour information plays an important role in classifying skin lesion. However, colour
identification by dermatologists can be very subjective, leading to cases of misdiagnosis …

Both image compression based on color quantization and image segmentation are two
typical tasks in the field of image processing. Several techniques based on splitting …

Abstract-The storage and transmission of imagery become more challenging task in the
current scenario of multimedia applications. Hence, an efficient compression scheme is …

Although quad-trees are not the most successful strategy in image coding, some
generalized subdivision schemes have been proposed recently. This work exploits a …
