Hierarchical Motion Estimation Algorithm Based on Pyramidal Successive Elimination

In this paper, we propose a hierarchical three step search algorithm using pyramid hierarchy. Hierarchical Minkowski inequality is adopted to reduce the cost of the sum of absolute difference (SAD) computations. A top-town procedure is developed to search motion vectors hierarchically and the search pattern used in the well-known Three Step Search (TSS) is adopted. We also propose a hybrid moti...

An Efficient Successive Elimination Algorithm for Block-Matching Motion Estimation

Low power VLSI video compression processors are in high demand for the emerging wireless video applications [1]. Video compression processors include VLSI implementation of a motion estimation algorithm. Many motion estimation algorithms are found in the literature. Some of them are fast but can not guarantee an optimal solution; they can be stuck in a local optima. Such algorithms are fast, co...

Modified 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...

A Sum Square Error based Successive Elimination Algorithm for Block Motion Estimation

Block Motion Compensation is used for finding and compressing temporal differences between frames and estimating the motion between frames. Optimal temporal compression demands minimising the error between blocks and this is best accomplished by having as large a search area as possible. Motion estimation, on the other hand, demands a small search area to preserve the coherence of the motion ve...

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...
