Abstract
An image segmentation method for segmenting various regions of digital radiographic images first uses progressively smoothing techniques to generate smoothed images at multiple scales (resolutions). Next, texture measures are computed at each scale for each pixel in the smoothed image. Then a clustering algorithm is applied to the feature space spanned by the vector of texture measures. A segment spectrum, which is the number of clusters as a function of scale, is subsequently constructed to determine the most stable range of scales and the most stable number of regions into which the image is best segmented. Each pixel in the image is then classified into one of the detected regions according to its belonged cluster in the feature space. Region filling is then performed to eliminate small holes in each segmented region. Finally, a segmented map is generated to function as multivalued templates for any further image processing to be done on various segmented regions of the image.
