Low-complexity block-based motion estimation via one-bit transforms
We present an algorithm and a hardware architecture for block-based motion estimation that involves transforming video sequences from a multibit to a one-bit/pixel representation and then applying conventional motion estimation search strategies. This results in substantial reductions in arithmetic and hardware complexity and reduced power consumption, while maintaining good compression perform...
متن کاملModified 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 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 Modified Two-Bit Transform
Modified two-bit transform based block motion estimation is presented in this paper. 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 local or full searches using the MAD ...
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...
