Text is extracted from a grayscale or color compound digital image. Kernels of text in the compound digital image are found using a stroke operator. The kernels of text are segmented into text blocks based on image space, color space, and intensity space. Each text block is segmented into text and background pixels using active contour analysis. The segmented text blocks are refined by altering parameters in the active contour analysis. Text is extracted from the refined segmented text blocks, and a binary image is created including text extracted from the refined segmented text blocks.
