摘要： Disclosed are an image processing apparatus and an image processing method. The image processing apparatus comprises a matching degree calculation unit configured to calculate respective matching degrees between an image waiting for processing and plural training images whose Kansei scores are pre-designated; and a Kansei score calculation unit configured to extract, from the plural training images, a predetermined number of training images corresponding to the maximum matching degree, and then based on the Kansei scores of the extracted training images with regard to a selected Kansei type, calculate a Kansei score of the image waiting for processing.

摘要： Disclosed are an image enhancement method, an image enhancement device, an object detection method, and an object detection device. The image enhancement method comprises steps of (a) letting an input image be a waiting-for-enhancement image and detecting specific objects in the waiting-for-enhancement image; (b) determining, based on an image feature of an object area including the detected specific objects, an image enhancement parameter so that an after-enhancement image enhanced according to the image enhancement parameter points out the image feature; (c) enhancing the waiting-for-enhancement image; (d) detecting the specific objects in the after-enhancement image; and (e) determining whether a predetermined stopping condition is satisfied. If the predetermined stopping condition is satisfied, then the after-enhancement image having a best result of object detection up to now is output; otherwise the after-enhancement image serves as the waiting-for-enhancement image, and steps (b) to (e) are carried out repeatedly.
