A mechanism for improving connectivity processing of computer axial tomography and magnetic resonance images by a fast, stack independent, iterative method first designates a pixel of an object material of interest in an image as a seed pixel. The mechanism then performs connectivity processing by starting at the seed pixel and evaluating the next forward direct neighbor pixel to determine if it is within the object material of interest. If the direct neighbor pixel is within the object, the direct neighbor pixel is marked as a new seed pixel and the connectivity mechanism evaluates the next forward direct neighbor pixel, continuing in a left-to-right and top-to-bottom fashion. Once forward processing of all pixels is complete, and if at least one pixel has been identified as a new seed pixel, the connectivity mechanism evaluates, in a backward progression, unevaluated pixel within the image, beginning at the lower right-most pixel in the image and proceeding through the pixels in a right-to-left, bottom-to-top fashion.
