This is a basic program that can track the shape of a blob in a photo. The traced contours can then be saved to a black and white mask image.

• png
• jpeg
• tif
• bmp

1. high filter pass
   • enable - sharpens corners so they are easier to detect.
   • sigma - higher increases edge constrast however significantly slows down program.
2. brightness threshold
   • offset - lower will include more objects but could introduce false positives.
3. errosion
   • enable - removes pixels at threshold border. Useful to detach false positives/noise near a cell's edge.
   • kernal size - how many pixels to delete for each errosion iteration. Large values will errode more but will also reduce resolution of image.
   • iterations - how many times to perform the errosion operation. Large values will errode more but will take longer.
4. dilation
   • enable - add pixels at threshold border. Useful to close small gaps between contours.
   • kernal size - how many pixels to add for each errosion iteration. Large values will add more but will also reduce resolution of image.
   • iterations - how many times to perform the dilution operation. Large values will dilute more but will take longer.
