EdgeTrak - Automatic Contour Tracking in Ultrasound Images

EdgeTrak is a program for tracking contours in sequences of black and white images, such as ultrasound images. Open-contours are extracted from the lower edge of a white to black gradient image.
The program reads in a sequence of .jpg (or .ras, .tif) images (that have sequential numbers in the file names) and tracks contours in them. It can export all or a subset of the contours in a .ts file as a .con file. It can save a palate trace, to superimpose on subsequent image files, as a .pal file. The exports are text files containing a series of coordinate points.
