In this paper, a local covariant region detection algorithm is proposed based on image contour corners. We define the corner response function as the DoB (Difference of B-spline) norm of the evolution difference of the image contour. A new feature region detection algorithm is designed combining corner points from the DoB algorithm and the scale invariance(More)
This study proposes a new method for the detection of local invariant features with contour. This method differs from traditional methods that use image intensity. Image contours can be extracted stably with changes in viewpoint, scale, illumination and other factors. The proposed algorithm first extracts the stable corner from the contour, then it fits the(More)
T h e audio quality, robustness and complexity issues of a novel mobile digital audio broadcast (DAB) scheme a re addressed. T h e audio codec is based on a combination of subband coding (SBC) and mult ipulse excited linear predictive coding ( M P L P C ) , where the bi t allocation is dynamically adapted according t o both the signal power in different(More)
