IMAGE PROCESSING SYSTEM

An image processing system comprises a template matching engine (TME). The TME reads an image from the memory; and as each pixel of the image is being read, calculates a respective feature value of aplurality of feature maps as a function of the pixel value. A pre-filter is responsive to a current pixel location comprising a node within a limited detector cascade to be applied to a window withinthe image to: compare a feature value from a selected one of the plurality of feature maps corresponding to the pixel location to a threshold value; and responsive to pixels for all nodes within a limited detector cascade to be applied to the window having been read, determine a score for the window. A classifier, responsive to the pre-filter indicating that a score for a window is below a windowthreshold, does not apply a longer detector cascade to the window before indicating that the window does not comprise an object to be detected. 本发明公开了种包括模板匹配引擎(TME)的图像处理系统。所述TME从存储器读取图像；并且当正在读取所述图像的每个像素时，作为所述像素值的函数来计算多个特征图的相应特征
