Hand gesture interpretation is an open research problem in Human Computer Interaction (HCI), which involves locating gesture boundaries (Gesture Spotting) in a continuous video sequence and recognizing the gesture. Existing techniques model each gesture as a temporal sequence of visual features extracted from individual frames which is not efficient due to the large variability of frames at different...
The Markov random field (MRF) has been applied to modeling the connectivity constraints of the text in document images for tasks like binarization and rule-line removal. One challenge of applying the MRF is its high computational cost. This paper presents a method using two nested set of states trained to reduce the computational cost of patch-based MRF. The two sets of states are trained at different...
The combination of biometric matching scores can be enhanced by taking into account the matching scores related to all enrolled persons in addition to traditional combinations utilizing only matching scores related to a single person. Identification models take into account the dependence between matching scores assigned to different persons and can be used for such enhancement. In this paper we compare...
