Reduced DCT approximations for low bit rate coding
Transform approximations are explored for speeding up the software compression of images and video. Faster approximations are used to replace the regular DCT whenever only few DCT...

Improved Entropic Edge-Detection
Using the Jensen-Shannon divergence of grey level histograms obtained by sliding a double window over an image, an edge-detector is presented. A new technique for linking unconnec...

Comparison of local feature descriptors for mobile visual search
We evaluate the performance of MPEG-7 image signatures, Compressed Histogram of Gradients descriptor (CHoG) and Scale Invariant Feature Transform (SIFT) descriptors for mobile vis...

A Robust Image Mosaicing Technique Capable of Creating Integrated Panoramas
Existing featureless image mosaicing techniques do not pay enough attention to the robustness of the image registration process, and are not able to combine multiple video sequenc...

All-Clear Image Based Synthesis using Clarity Degree
Image based rendering (IBR) usually produces severe artifacts, typically blur and ghost, for objects not located on the focal plane. To obtain an all clear result, previous works ...
