Yes one great thing that helped was increasing the fuzz to 10%. that seems to work well. Thank you again for all your help. its hard to understand imagemagick. I really wish there was a more thorough book out there thats up to date. ill have to go through documenation for now. Do you know of any ...

Hey it works great! the only issue im having is that the images arent cropping to exactly the same in the master sheet. For instance ill have 2 or more images in the one master sheet ...200x300, 425 x 500 .. . im using the command below: convert niceoutput-chopped.png -define connected-components ...

i want to mask the whole ipad, starting from the white outer portion. so in the end it should look like in the image below but better (the image still has some black leaking in the white areas

Use as small a fuzz value as you can. For JPG images, the compression makes the background uneven. I have found values ...
