Remarks

The java language needs a lot of additions and improvements before it can rival C++. The code also runs very slow compared to code compiled with a C++ compiler.

We tried to implement as many things as we could within the time allotted for the project. However, at some point we decided to do everything for color images since it seemed more attractive. This made things complicated and prevented us from doing more in this short period of time. Currently, the auto thresholding algorithm is incomplete since it needs a contrast image to decide the best threshold and it is slightly more involved to calculate the contrast image of a color image. We have successfully completed the implementation of the contrast image calculation but have not added it to the final applet. The contrast image was calculated using methods similar to what Ismail and David use in their effort to improve the color segmentation portion of the Pfinder and looks a lot better than the results from the Sobel and Prewitt operators. We plan to add more operations to the applet during the summer and hope to have a nice tool with all the basic image processing algorithms by the end of summer. The applet in its current state can be found at http://www.umiacs.umd.edu/users/vasi.
