    摘要: An image processing apparatus and method for real time motion detection is provided. In the apparatus, a sub-sampling module receives and sub-samples a current image and a plurality of previous images and a census transform module performs census transform on each of the sub-sampled images to obtain a census vector. A correlation calculation module calculates and compares correlation values between the current image and the plurality of previous images and detects a region having highest correlation. A motion detection module tracks positions of pixels corresponding to the region having the highest correlation to detect motion information in the images. The image processing apparatus and method can obtain, in real time, the direction and speed of an object that is in motion in each image.

    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 are a system and a method extensible for performing, in real-time, stereo snatching for calculating depth images with a result of searching for points of similarity by using images taken with two cameras. The system includes a coordinate creating module, a census transform module, a delay XOR calculation module, a stereo matching module, and a control module. Accordingly, by using the system extensible for performing stereo matching, depth information of corrected images can be acquired in real-time without using computer systems or software programs for special purposes. Furthermore, since the system extensible for performing stereo matching can be simply realized by hardware, the system and the method of the present invention can be easily applied to actual intellectual-type robots, industrial settings, etc.
