Abstract: A method for detecting orientation of the contours in an image, performs an initial transformation of the image using a non-decimated multi-resolution transform, segments the image into a plurality of blocks, determines the optimal resolution for each block, and detects the predominant direction of contour for each of the blocks.

Abstract translation: 一种用于检测图像中轮廓的取向的方法，使用非抽取的多分辨率变换来执行图像的初始变换，将图像分割成多个块，确定每个块的最佳分辨率，并且检测主要 每个块的轮廓方向。
