DEVICE, METHOD AND COMPUTER READABLE STORAGE MEDIUM THEREOF FOR DETECTING OBJECT

Taiwan, Province of China

Overview

A method for detecting objects is provided. The method comprises the steps outlined below. An image having pixels is acquired. Image blocks each corresponding to one of the pixels are generated. A specific image block is filtered using N filtering parameters that gradually enhance the blurriness of the specific image block to generate N filtering results. N RMSE values are computed, in which the M-th RMSE value is computed according to the M-th and the (M?1)-th filtering results. A slope of an approximate line is computed according to the RMSE values as the blurriness value of the specific image block. The above steps are repeated to generate the blurriness values of all the pixels. The blurriness value is compared to a threshold value to detect sharp pixels which are parts of a sharp object and further detect an in-focus object.
