Outline of Final Research Achievements

It is getting attention to recognize objects from a image. There are a lot of researches have been proposed and most of them uses statistical learning and recognition such as bag of features of intensity pattern of the object. However, this kind of approach cannot directly apply to transparent object recognition, since the appearance and the intensity patten of the object is drastically changed by background appearance. So the previous approach have been ignored the transparent objects from the target object. We proposed new approach and methods to handle the transparent objects in object recognition. We proposed light field distortion feature (LFD) for describing the object. The feature describes the distortion of light field cased by refraction of the transparent objects. We used the LFD feature and realized to object classification and segmentation of the objects as the applications.
