This paper presents an efficient hardware architecture for motion estimation (ME) in high resolution digital videos. This architecture is built upon the new Multi-Point Diamond Search algorithm (MPDS) which is a fast algorithm that increases the ME quality when compared with other fast algorithms. The MPDS is able to reduce local minima falls, increasing(More)
Motion estimation (ME) is the most important component of current video encoders, however, it presents a very high computational complexity. To deal with this complexity, fast ME search algorithms are widely used, since they can greatly speed up this process. Fast search algorithms are vulnerable to choose local minima, producing quality losses, and these(More)
This paper presents the architectural design for Motion Estimation (ME) based on the new Multi-Point Diamond Search block matching algorithm. This algorithm reduces the local minima falls in the ME search process, increasing the quality of the ME prediction results. This paper presents a software evaluation about the MPDS which presented an average PSNR(More)
—In this paper, we propose two new algorithms for high quality motion estimation in high definition digital videos. Both algorithms are based on the use of random features that guarantee robustness to avoid dropping into a local-minimum. The first algorithm was developed from a simple two stage approach where a random stage is complemented by a greedy stage(More)
This paper presents a new method for high efficiency video coding using an adaptive GOP structure based on video content for the H.264/AVC standard. The available H.264/AVC encoders typically use static GOP sizes that define how the frames I (Intra), P (Predictive) and B (Bi-predictive) are positioned during de coding process. However, by analyzing the(More)
This paper presents a high throughput and low hardware cost architecture for motion estimation (ME) using a Quarter Subsampled Diamond Search algorithm (QSDS) with Dynamic Iteration Control (DIC). QSDS-DIC is a new algorithm proposed in this paper, which was developed to focus an efficient hardware design of ME. QSDS-DIC is based on the well known Diamond(More)
This paper presents a new mode decision for the depth maps intra-frame prediction in 3D-HEVC. The proposed technique decides if the traditional High Efficiency Video Coding-based (HEVC) intra-frame prediction should be performed or skipped. This technique is inspired by the fact that traditional intra-frame prediction may generate artifacts in the(More)
This work presents a hardware design for the Sample Adaptive Offset filter, which is an innovation brought by the new video coding standard HEVC. The architectures focus on the encoder side and include both classification methods used in SAO, the Band Offset and Edge Offset, and also the statistical calculations for the offset generation. The proposed(More)
