Region Quad-Tree Decomposition Based Edge Detection for Medical Images
Edge detection in medical images has generated significant interest in the medical informatics community, especially in recent years. With the advent of imaging technology in biomedical and clinical domains, the growth in medical digital images has exceeded our capacity to analyze and store them for efficient representation and retrieval, especially for data mining applications. Medical decisio...
متن کاملQuad-pixel edge detection using neural network
One of the most fundamental features of digital image and the basic steps in image processing, analysis, pattern recognition and computer vision is the edge of an image where the preciseness and reliability of its results will affect directly on the comprehension machine system made objective world. Several edge detectors have been developed in the past decades, although no single edge detector...

متن کاملQuad-tree Decomposition Based Image Analysis Using Intensity Difference Threshold
The watermark bit assignment controls the watermark embedding strength and the bit plane selection. Quad-tree decomposition is used as analysis technique which involves subdividing of image into blocks that are more homogeneous in comparison to the image itself. This technique gives the information about the structure of the image. This is the first step in adaptive compression algorithms. For ...
