Inspired by the serum pooling strategy in medical area, this paper presents a new approach for video fingerprint search. The proposed method has adopted the serum pooling strategy to reduce the unnecessary matching calculation during the search process. Two observations about random vectors are given, which enable us to obtain a general similarity measure and accelerate the search speed without losing...
In this paper, two energy minimization based image segmentation methods are investigated. The formulations of both methods-level set and Otsu thresholding-are detailed. Several experiments are carried out and the comparison is conducted in terms of segmentation results, CPU time cost and adaptability to multi-phase images. The pros and cons of the methods are also discussed. As a by-product, we propose...
