Fast Trilateral Filtering

This paper compares the original implementation of the trilateral filter with two proposed speed improvements. One is using simple look-up-tables, and leads to exactly the same results as the original filter. The other technique is using a novel way of truncating the look-up-table to a user specified required accuracy. Here, results differ from those of the original filter, but to a very minor ...

Novel Frame Rate Up-Conversion Method Through Weight Matching Criterion and Motion Vector Refinement

This paper presents a novel frame rate up-conversion (FRUC) framework using regulations matching criterion. Motion estimation is one of the key elements in FRUC, and the regularization matching criterion using the difference of Gaussians (DOG) is proposed to improve the motion estimation accuracy. The proposed FRUC framework has three steps. First, the initial motion vector field is calculated ...

sMAE: An Improved Block Matching Criterion

In this paper a new variation of the well known MAE (Mean Absolute Error) matching criterion for video coding applications, is introduced. The MAE criterion is simpler than the MSE criterion because of the lack of multiplication operations, but it achieves a lower performance in terms of PSNR and MSE. In this work we impose an additional statistical constraint over the MAE thus filling the perf...

Trilateral Filtering: A Non-linear Noise Reduction Technique for MRI

INTRODUCTION Filtering is a preliminary process in many medical image processing applications, which is aimed at restoring a noise-corrupted image to its noiseless counterpart. Post-processing tasks, e.g., visualization, segmentation and quantification, may benefit from the reduction of noise. Diffusion equations with scalar-valued and tensor-valued diffusivities [1] and non-linear filters [2] ...

Improved H.263+ Rate Control via Variable Frame Rate Adjustment and Hybrid I-Frame Coding

A novel rate control algorithm consisting of two major components , i.e. a variable encoding frame rate method and a hybrid DCT/wavelet I-frame coding scheme, is proposed in this work for low bit rate video coding. Most existing rate control algorithms for low bit rate video focus on bit allocation at the macroblock level under a constant frame rate assumption. The proposed rate control algorit...
