A method of speeding up image detection, adapted to increase a speed of detecting a target image and enhance efficiency of image detection, comprises the steps of capturing an image; retrieving a plurality of characteristic points of the image; creating a region of interest (ROI) centered at the characteristic points each; creating a plurality of search point scan windows corresponding to the ROIs, respectively; calculating target hit scores of the characteristic points and the search point scan windows; comparing the target hit scores of the characteristic points and the search point scan windows to obtain an ROI most likely to have a target image; calculating centroid coordinates of the ROI by a centroid shift weight equation; and narrowing a scope of ROI search according to a location of the centroid coordinates and reducing a displacement between the search points.

Method of speeding up image detection

A method, a system, and a computer program product for object color correction are provided. Two images of the same target provided by two image capturing devices are introduced into an image conversion model constructed by an image conversion algorithm, and a color coefficient and a luminance coefficient for color space conversion are found, so as to convert the two images to a target color space. Then, the two images in the target color space are introduced into an image color distribution space model constructed by the image conversion algorithm, so as to obtain two different image color distribution space principal axes. The two image color distribution space principal axes are compared and adjusted to be parallel, thereby adjusting a color difference between the two images. The two images that are adjusted are converted back to an original color space, so as to obtain the two corrected images.
