Mask Image not shown during object trining

[AsaadIrfan]

I'm trying to capture objects for training and i dont get any masked image,although i have trained objects successfully several times before using the same set of commands as mentioned here: https://groups.google.com/forum/#!msg/object-recognition-kitchen/ijpfJdG9q8E/FPG4HtRBr4AJ

Here are a few snapshots of the "blank masked image":

so what changed ? Did you update the code or just some ROS packages ?

I didn't change the code. However, i did re-install the same OR packages multiple times because of a few OS problems.
