A nonlinear loop filter for quantization noise removal in hybrid video compression
We propose a high-performance, nonlinear, loop filter that reduces quantization noise over video frames composed of locally uniform regions (smooth, high frequency, texture, etc.)...

Quad-Tree Segmentation for Texture-Based Image Query
In this paper we propose a technique for segmenting images by texture content with application to indexing images in a large image database. Using a quad-tree decomposition, textu...
