This paper presents interpolation-free fractional-pixel motion estimation (FME) algorithms and efficient hardware prototype of one of the proposed FME algorithms. The proposed algorithms use a mathematical model to approximate the matching error at fractional-pixel locations instead of using the block matching algorithm to evaluate the actual matching error. Hence, no ...

This paper presents low-complexity algorithm for fractional-pixel motion estimation (FME). The proposed algorithm uses a mathematical model to approximate the matching error at fractional-pixel locations. Hence, no interpolation is required at fractional-pixel locations. The matching error values at integer-pixel locations are used to evaluate the model coefficients. The performance of ...

The H.264 video coding standard supports the usage of Variable Block Size (VBS) Motion Estimation/ Compensation and Mode Decision (ME/MD). This tool clearly enhances the rate-distortion (R-D) capabilities of the encoder. However, it dramatically increases its computational requirements. This paper represents an extension to a recently proposed scheme for efficient ...
