This paper presents a video resizing approach that provides both efficiency and temporal coherence. Prior approaches either sacrifice temporal coherence (resulting in jitter), or require expensive spatio-temporal optimization. By assessing the requirements for video resizing we observe a fundamental tradeoff between temporal coherence in the background and shape preservation for the moving objects...
A novel shape similarity measure based on membership function is proposed in this work to make the measure more consistent with human perception and improve the matching accuracy. The proposed method commences with extraction of feature vectors of shapes in training shape set, then a fuzzy set over each eigenvalue space is defined. The membership function of the fuzzy set is defined and acts as a...
An example-based floral pattern generation approach is proposed in this paper to improve the aesthetic design ability of computer, which will enable user's simple draft to be converted to an aesthetic pattern with a few interactions. The proposed approach commences with introducing artists work into the system by example patterns they drew. User's draft is segmented into elements, shape features of...
