    摘要： A device for detecting a shadow region in an image includes an imaging module generating a multi-channel image including brightness, red, green, and blue channels, a brightness correcting module correcting values of the brightness channel based on imaging parameters and outputting a corrected multi-channel image, a scene classifying module determining to carry out a shadow detection on the corrected multi-channel image, a shadow detecting module classifying pixels of the corrected multi-channel image into a shadow or non-shadow pixel, and generating a shadow classification mark matrix having pixels having a shadow classification mark value corresponding to the classification, a region segmentation module segmenting the multi-channel image into regions having pixels having similar color values, and generating a region mark matrix having pixels having a region mark value, and a post-processing module updating the shadow classification mark matrix based on the shadow classification mark matrix and region mark matrix.

    摘要： System, method, and computer-readable medium for seeking representative images in an image set. Text features of each of the plural images are extracted. Diversity data of the image set is obtained based on the text features. A representative score of each of the plural images is calculated based on the diversity data. One or more of the images in the image set is selected as a representative image based on the representative score of the corresponding images.

    摘要： Disclosed is a sky detection system that detects sky in an image collection device. The system includes an image collection unit that collects information of a color image; a color-feature extraction unit that extracts a color feature of each pixel from the collected image; a distance measurement unit that measures a distance between each pixel of the collected image and a lens; a first classification unit that classifies each pixel of the collected image as either a sky pixel or a non-sky pixel based on the color feature; and a second classification unit that further classifies each pixel of the collected image as either the sky pixel or the non-sky pixel based on the distance and a result of the first classification unit.
