A 40 × 35 × 25-mm3 specimen of human breast consisting mostly of fat and connective tissue was imaged using a 3-T magnetic resonance scanner. The resolutions in the image plane and in the orthogonal direction were 130 μm and 150 μm, respectively. Initial processing to prepare the data for segmentation consisted of contrast inversion, interpolation, and noise reduction. Noise reduction used a multilevel...
We present a methodology for characterizing small size heterogeneous textures that are hard to analyze in general due to the paucity of pixels and textural heterogeneity. The methodology overcomes the limitation for a large class of heterogeneous textures that exhibit onion layer type textural variation, where we may assume that within a layer the behavior is homogeneous, but may vary from layer to...
In this paper, we describe a method to detect human fingers from images captured by a stereo camera. The images captured by the stereo camera are preprocessed by a skin detection module. Two hands are extracted from the skin regions using disparity information. We then apply grayscale morphology and use BLOB analysis to detect fingers and their directions. The method is simple yet powerful for finger...
