    This paper first reviewed the two-dimensional discrete cosine transform (2-D DCT) and inverse DCT (IDCT) architectures. Then a new VLSI architecture, namely the transpose free row column decomposition method (TF-RCDM), for 2-D DCT/IDCT is proposed. The new RCDM architecture replaces the transpose circuits with permutation networks and parallel memory modules. As results, the timing overhead of I/O... View full abstract»

    This paper proposes an efficient two-dimensional (2-D) discrete cosine and inverse discrete cosine transform (DCT/IDCT) core design. Adopting the row-column decomposition technique for computing 2-D DCT/IDCT, we formulate the one-dimensional (1-D) DCT/IDCT into cyclic convolution by properly arranging the input sequence, optimize the multiplications based on the concept of common subexpression sha...

    A subsampling structure, an N-Queen lattice, for spatially decimating a block of pixels is presented. Despite its use for many applications, we demonstrate that the N-Queen lattice can be used to speed up motion estimation with nominal loss of coding efficiency. With a simple construction, the N-Queen lattice characterizes the spatial features in the vertical, horizontal, and diagonal directions f... View full abstract»

    This paper presents a novel error detection and correction methodology for corrupted discrete cosine transform (DCT) coefficients caused by the transmission of DCT coded images over a noisy wireless channel. This method is based on the properties of DCTs and the transmission of exact intensity values of a few reference pixels. These allow us to identify the error pattern and correct the corrupted ...

    It is well known that at low-bit-rate block discrete cosine transform compressed image exhibits visually annoying blocking and ringing artifacts. In this paper, we propose a noniterative, wavelet-based deblocking algorithm to reduce both types of artifacts. The algorithm exploits the fact that block discontinuities are constrained by the dc quantization interval of the quantization table, as well ... View full abstract»

    This paper addresses the problem of extracting video objects from MPEG compressed video. The only cues used for object segmentation are the motion vectors which are sparse in MPEG. A method for automatically estimating the number of objects and extracting independently moving video objects using motion vectors is presented here. First, the motion vectors are accumulated over a few frames to enhanc... View full abstract»

    A novel image sequence segmentation method which combines both spatial and temporal information is presented in this paper. The first step is an intensity segmentation scheme based on the edgeflow method. The temporal information is introduced through three-dimensional (3-D) motion estimation parameters. In the second step, regions obtained from the first step are clustered according to their 3-D ... View full abstract»

    Text presented in videos provides important supplemental information for video indexing and retrieval. Many efforts have been made for text detection in videos. However, there is still a lack of performance evaluation protocols for video text detection. In this paper, we propose an objective and comprehensive performance evaluation protocol for video text detection algorithms. The protocol include... View full abstract»

  • Flicker correction for archived film sequences using a nonlinear model

    A new model for the correction of flicker in archived film sequences is formulated from first principles. The model takes into account the Hurter-Driffield density versus log exposure characteristic to estimate image intensity errors caused by exposure inconsistencies. The model is shown to be highly nonlinear and can accommodate typical grayscale manipulations performed during film-to-video trans... View full abstract»

  • An efficient method for DCT-domain separable symmetric 2-D linear filtering

    We propose an efficient method for separable symmetric linear filtering in the discrete cosine transform (DCT) domain. First, separable two-dimensional (2-D) linear filtering is decomposed into the cascade of one-dimensional filtering in the DCT domain. We investigate special characteristics of DCT domain filtering matrices when the filter coefficients are symmetric. Then we present the DCT-domain... View full abstract»

    It is a well-observed characteristic that, when a discrete cosine transform block is traversed in the zigzag order, ac coefficients generally decrease in size and the runs of zero coefficients increase in length. This paper presents a minor modification to the Huffman coding of the JPEG baseline compression algorithm to exploit this characteristic. During the run-length coding, instead of pairing ...

    A major problem in object-oriented video coding and MPEG-4 is the encoding of object boundaries. Traditionally this problem is treated separately from the texture encoding problem. In this paper, we present a vertex-based shape coding method which is optimal in the operational rate-distortion sense and takes into account the texture information of the video frames. This is accomplished by utilizin... View full abstract»

    This paper offers a natural extension of the newly introduced "anti-face" method to event detection, in both the gray-level and feature domains. For the gray-level domain, spatio-temporal templates are created by stacking the individual frames of the video sequence, and the detection is performed on these templates. In order to recognize the motion of features in a video sequence, the spatial loca... View full abstract»

    We present a new wavelet video coding algorithm and an optimization framework that allocates bits efficiently among consecutive frames at the pixel level. The video residual coder is based on set partitioning in hierarchical trees and wavelet blocks, allowing flexible bit allocation among active and inactive regions in a video frame. To optimize the encoder for efficient bit allocation, we use Lag... View full abstract»

    An adaptive unequal channel protection technique is proposed for JPEG2000 compressed images exploiting the hierarchical structure of the coded bit stream. The proposed technique takes into account the effect of the channel errors in different packets of the bit stream in order to optimally protect the coded data according to the channel conditions. The robustness of the proposed technique is evalu... View full abstract»

    It is known that the human visual system (HVS) does not pay equal attention to each error and even region in judging picture quality. In this paper, we combine a perceptual model with an integrated detection of the spatially transitional regions in visual distortion evaluation to better match the HVS perception to visual quality. For decompressed images or video, the spatially transitional regions... View full abstract»
