Subject: magic wand and tracking


sorry for my bad English

I try to do the 2 things as follow with Delphi 5, could you tell me if Envision (full lib, I will purchase it if it works) can help me and eventually how

1) magic wand like
user click on an object (generally a ball) drawn on a bitmap RGB
I would like to detect object's edges and copy its area in a GDI region (HRGN)

2)to search for my object above in other bitmaps, or at least the most similar area in these other bitmaps

thanks very much for information and help, unfortunatly for me my image analysis knowledge is very poor
