An analysis of subjective quality in low bit rate video
A subjective quality evaluation was performed to quantify viewer responses to various visual defects that appear in low bit rate video, both at full and reduced frame rates. The s...

Anti-geometric diffusion for adaptive thresholding and segmentation
In this paper, we present a novel adaptive thresholding technique based upon an anisotropic diffusionmodel, whichmay be referred to as the anti-geometric heat flow. In contrast to...

Scale space segmentation of color images using watersheds and fuzzy region merging
A multi-resolution segmentation approach for color images is proposed. The scale space is generated using the Perona-Malik diffusion approach and the watershed algorithm is employ...

A comparative evaluation of algorithms for fast computation of level set PDEs with applications to motion segmentation
We address the problem of fast computation of level set partial differential equations (PDEs) in the context of motion segmentation. Although several fast level set computation al...

Hyperspectral image coding using 3D transforms
This work considers the efficient coding of hyperspectral images. The shape-adaptive DCT is extended to the three-dimensional case. Both the 3D-SA-DCT and the conventional 3D-DCT ...

All-integer Hough transform: performance evaluation
The Hough transform is a widely used tool for line detection mainly due to its robustness to noise; on the other hand, it is also known to be computationally expensive, thus often...
