    摘要: Disclosed herein is an image processing method and apparatus for detecting the lines of images and the start and end points of the lines. The image processing apparatus includes an edge creation unit, a Hough transform unit, and an effective parameter detection unit. The edge creation unit creates an edge image using external image data input from the outside. The Hough transform unit performs a Hough transform on information about the pixel coordinates of the edge image created by the edge creation unit. The effective parameter detection unit detects the lines of the edge image by checking effective line parameters using the results of the Hough transform. The image processing apparatus may further include an edge list for storing coordinates of effective pixels constituting the edge image and a line parameter list for storing the effective line parameters.

    摘要: Disclosed herein is a real-time face detection apparatus. The real-time face detection apparatus includes a down-scaling unit and a face region comparison unit. The down-scaling unit down-scales an input image at at least one ratio. The face region comparison unit creates a plurality of windows for the image down-scaled at the at least one ratio, acquires face region confidence of each of window images within the created windows by comparing the window image with a classifier, and determines whether the window image corresponds to a face region.
