Text extraction is one of most interest for
researchers. In this paper, we propose a new robust and
efficient algorithm to become such a software extracts text of
colored book and journal cover sheets is. First, we perform
wavelet decomposition. Next for edge detecting from detail
coefficients, we use a dynamic threshold. By blurring
approximate coefficients with alternative heuristic
thresholding, considering horizontal coefficient, achieve
effective edge. Afterward, ROI technique get binary image.
Finally, text boxes would be extracted with new projection
profile.
