Transform OpenCV image data type to Devil image format and vice-verca

Question

I want to use a CUDA-enabled SIFT library but I am using the OpenCV driver to get images from the webcam? The Cuda library is using the Devil Library for image data types. Should I transofrm the images from OpenCV data types to Devil? Or Should I use another method for getting images from the webcam[devil compatible data types]? Thanks for your attention

Answer 1

I am not familiar with the DeviL but from the manual it states that it supports the following formats:

IL_COLOUR_INDEX
IL_RGB
IL_RGBA
IL_BGR
IL_BGRA
IL_LUMINANCE

of varying bit depths.

When loading images, OpenCV also supports most of these image types and bit depths and conversion between them is pretty straightforward (see the convertTo() function in the openCV documentation) . Using a webcam may be more complex.

It is difficult to answer your question directly without knowing the interface of the specific library. If the library accepts a devil image in a specific form, then it is likely you will have to give it in that form. OpenCV will likely be able to output data in the required form; if not, you may have to write code to transform it yourself.
