The JPEG method is used at various compression rates determined by a single parameter. The authors' metrics are specifically targeted to measure the degree of invariance of the processing to the presence of a compression-decompression step and not absolute processing success. The detection of the /spl mu/Ca++s is done with a two-step process of selective median filtering and wavelet domain hard thresholding with saturation. This latter step produces a binary image revealing small structures which are the desired objects in the image. The authors have also chosen to perform the enhancement before the compression step as suggested by their previous work to allow higher compression rates. In the system used to do the comparison, the two branches of processing are identical except for the compression/decompression step and their results are binary images. The inputs to the metric computation system are these two images which produce four scalar metrics which are various percentages of differences in pixel and region activity. Using seven image sections from mammograms, the authors illustrate the results at various compression ratios in the range 28:1 to 42:1 for each image and also averaged over the set of seven. The three pixel based metrics decrease monotonically as the JPEG compression quality parameter increases to reduce the compression ratio. The region based metric does not change monotonically due to the more complex nature of region analysis.","PeriodicalId":373701,"journal":{"name":"1998 IEEE Southwest Symposium on Image Analysis and Interpretation (Cat.

Conventional shape-change models like optical flow, deformable templates, etc., primarily address rigid and non-rigid deformations which are not in the form of growth. Moreover the above models assume the shape-change between successive frames in an image sequence to be small which is not true in many real-world biomedical image sequences. The Active Contour Model presented here tracks the boundary of an object as it changes shape and can also predict how the object might change shape. The algorithm is an energy minimization technique which tracks the growth of a specimen by attracting a closed piecewise cubic curve to the boundary of the specimen in every image of a sequence. This method computes shape-change especially when it is in the form of growth-better than techniques like optical flow, deformable templates, etc. Unlike conventional shape-change algorithms, the authors' algorithm can be applied iteratively to compute drastic shape-changes also. The authors also propose a parallel framework to facilitate real-time implementation.","PeriodicalId":373701,"journal":{"name":"1998 IEEE Southwest Symposium on Image Analysis and Interpretation (Cat.
