#Image Warping Tool

##Working:

• open/capture/display two images
• draw/edit/delete lines, with corresponding lines on the other image.
• save/open project
• render settings: number of frames, values of a, b, and P in the weight equation
• render images: multithreaded, progress view, sparse sampling technique to speed up rendering
• playback images: finger-slide to show animation, frame-forward/frame-backward buttons.

##User Guide:

###Screen 1: (ShowImages.java)
