The basic framework of depth completion is to predict a pixel-wise dense depth map using very sparse input data. In this paper, we try to solve this problem in a more effective way, by reformulating the regression-based depth estimation problem into

An error resilient three-dimensional (3-D) mesh coding system is proposed in this paper. The encoder uses a shape adaptive data partitioning scheme to alleviate the effect of error propagation. An input mesh surface is coarsely divided into smooth an

This paper proposes an adaptive quantization algorithm for video coding using the information obtained from the previously encoded image. Before quantizing the discrete cosine transform coefficients, the properties of reconstruction error of each mac

A novel concept of channel division to improve the performance of distributed video coding is proposed in this work. At the decoder, the proposed algorithm partitions each side information frame into multiple regions with different expected distortio

We propose a novel video codec that can distribute computational complexity between the encoder and the decoder in a flexible manner. Since motion estimation is the most computationally intensive part in video coding, it is important to share the mot

A multiple description coding (MDC) technique for 3D surface geometry is proposed in this work. The encoder uses a plane-based representation to describe point samples. Then, those plane primitives are classified into two disjoint subsets or two desc

An algorithm for robust transmission of compressed 3-D mesh data is proposed in this work. In the encoder, we partition a 3-D mesh adaptively according to the surface complexity, and then encode each partition separately to reduce the error propagati

We propose an overlapped block motion compensation method, called adaptive windowing technique, to improve the performance of variable block-size motion compensation in H.264. First, we restrict the number of neighboring blocks to be overlapped. Then

In motion compensated video coding, if motion vectors are lost or received with errors, not only will the current frame be corrupted, but also the errors will propagate to succeeding frames. The effects of errors can be further magnified by the fact

In this paper, a VLSI architecture for Reed-Solomon (RS) decoder based on the Berlekamp algorithm is proposed. The proposed decoder provides both erasure and error correcting capability. In order to reduce the chip area, we reformulate the Berlekamp
