windows development community please help me
im deepak roy , doing my final year undergrad in computer science....
im doing a project - Motion detection and Tracking in vc++( video for windows). The project combines image acquisition, manipulation techniques with other image processing techniques and neural network approaches.
im using video for windows to capture images from a webcam( EZONICS CAM II ). if u have used video for windows, u might be knowing that in the VIDEO FORMAT DIALOG BOX there is a dropdown list box for selecting bitdepth. my application works really fine for bitdepth = 24 but when the user selects bit depth = 12 then it doesnt work properly
the main problem is , im not sure as to how i should interpret pixels in those 12-bit images. i tried one interpretation,
12-bits = 4-bit red + 4-bit green + 4-bit blue. but this interpretation is not working
one more problem is, im not sure whether the bitdepths( 24-bit RGB , 12-bit : 1420 ) appearing in the list box are something which the webcam supports or those options are available for all capture devices while workin with video for windows....if 12-bits is somethin my camera uniquely supports then i should probably consult the camera(EZONICS CAM II) documentation - but the camera documantation doesnt seem to provide any such information(im not sure)....
i would be very thankful to u , if u can help me( may be by telling me as to how to interpret pixels in those 12-bit images) y givin me a good advice..........please please please help me soon because i hv to show my application to my professor by monday..
