Modified one-bit transform for motion estimation
Motion estimation using the one-bit transform (1BT) was proposed in [1] to achieve large computation reduction. However, it degrades the predicted image by almost 1dB as compared with full search. In this paper, we propose a modification to the 1BT by adding conditional local searches. Simulation results show that the proposed modification improves the PSNR significantly at the expense of sligh...
متن کاملCombine the Multiple Candidates Search with One-bit Transform for Motion Estimation
Motion estimation using one-bit information (1BT) to represent a pixel or a group of pixels becomes popular in recently years [1-2] as the distortion function between the reference block and the search block can be computed very efficiently. In [1], each frame is filtered and compared with the original frame to extract the edge information. However, its performance is not good enough as it degr...
متن کاملFluid Injection Optimization Using Modified Global Dynamic Harmony Search
One of the mostly used enhanced oil recovery methods is the injection of water or gas under pressure to maintain or reverse the declining pressure in a reservoir. Several parameters should be optimized in a fluid injection process. The usual optimizing methods evaluate several scenarios to find the best solution. Since it is required to run the reservoir simulator hundreds of times, the process...
متن کاملModified Constrained Two-bit Transform for Motion Estimation
Motion estimation (ME) using bit-plane matching (BPM) algorithm has been proposed. The bit-plane matching algorithm transforms original images into bit-planes and performs a fast block matching process using the bit-planes. Two-bit transform (2BT) transforms an image frame into two bit planes with local window mean and variance values as threshold values. Constrained two-bit transform (C2BT) wa...
متن کاملBlock motion estimation using adaptive modified two-bit transform
An adaptive modification to the two-bit transform-based low-complexity block motion estimation approach is proposed. Initially, video frames are converted into two-bit representations using the two-bit transform (2BT), and binary block-based motion estimation is performed using these two bit-planes. Modification to the original 2BT-based motion estimation scheme is introduced by conditional loc...
