Joint Depth and Alpha Matte Optimization via Fusion of Stereo and Time-of-Flight Sensor
We present a new approach to iteratively estimate both high-quality depth map and alpha matte from a single image or a video sequence. Scene depth, which is invariant to illumin...

On Macroblock Partition for Motion Compensation
In the H.264/AVC video coding standard, motion compensation can be performed by partitioning macroblocks into square or rectangular sub-macroblocks in a quadtree decomposition. Th...

Rapid automated detection of roots in minirhizotron images
An approach for rapid, automatic detection of plant roots in minirhizotron images is presented. The problem is modeled as a Gibbs point process with a modified Candy model, in wh...

Condensing Image Databases when Retrieval is Based on Non-Metric Distances
One of the key problems in appearance-based vision is understanding how to use a set of labeled images to classify new images. Classification systems that can model human performa...
