Abstract:
1. An apparatus of detection an image object comprising: a noise filtering block for dividing an input image into multiple regions and removing image noise in the input image to produce a noise-removed image; an image scaling block for scaling the noise-removed input image to produce a scaled input image; a memory control block for temporarily storing the noise-removed input image, and the scaled input image, wherein the noise-removed image and the scaled image being transferred as a first input image and a second input image, respectively; an image conversion block for dividing the second input image into multiple regions and converting the divided image by a modified census transform (MCT) method; a data processing block for comparing MCT values of the image converted by the MCT method with a preset threshold value, detecting at least one candidate region, and identifying a human region from said at least one detected candidate region; and an image output block for marking the identified human region on the first input image.
