A new method for image coding in computer vision

A new method for image coding in computer vision

引用

IEEE Region 8 International Symposium on Video/image Processing and Multimedia Communications (EURASIP)

作者： J.I. Larrauri E. Kahoraho Department of Control and Industrial Electronics University of Deusto Bilbao Spain

In this paper, a new lossless method for real time compression of still images in the field of the artificial vision, is presented. the proposed method is based on a new focus which incorporates the simultaneous execution of the acquisition and compression process of an image. the method consists of three processes. In the first one, a linear camera captures a line which is stored in memory. In the next step, the compression process of this line is executed at the same time as the acquisition process reads the next line. the process is repeated downwards starting from the upper line of the image. the novelty and main contribution of this method is in the compression process. A new coding algorithm is formulated and developed. the proposed method guarantees a ratio of compression of 3:1 with high probability and a real time execution.

Transform coding based on the Karhunen-Loeve transform (KLT), the discrete cosine transform (DCT), and the discrete wavelet transform (DWT) is well-understood for optical images. Transform coding applied to synthetic aperture radar (SAR) data, however, has not been well-studied. this paper compares the results of compressing SAR images when it is available in Cartesian and polar formats. We compare the compression results based on six performance criteria-mean-squared error, mean absolute error, peak signal-to-noise ratio, energy compaction, transform gain, and compression *** both the formats the phase information of the compressed data is preserved to a great extent. A block adaptive Max quantizer is used with 1-5 bit quantization of the components. the quality of the reconstructed data is compared in terms of compression ratio and quality parameters: signal to noise ratio (SNR), standard deviation of the phase (PSD), and mean phase error (MPE). the parameters are calculated for SAR raw data, complex data and 8-bit gray scale image. Finally, original(Fig.4) and reconstructed gray scale images(Fig. 5) are presented.

In the era of intelligent media, we all need high quality image or video information. However, due to the limitation of bandwidth or storage resource, we usually use low bit rate coding technology for image compression. But the image distortion caused will bring in a visually inferior experience, and the actual information obtained is often not sufficient. therefore, the super-resolution reconstructed image coding technology is researched to provide a higher dynamic bit rate variation range. Based on image super-resolution reconstruction, this paper proposes two targeted image compression coding frameworks. Firstly, we compress the DCT down-sampled image as the input of super-resolution reconstruction, and use image completion as the pretreatment process of image super-resolution reconstruction, which effectively improves the quality of reconstructed image at low bit rate and, hence improves the coding efficiency. Secondly, a new image compression technique is proposed here which is based on residual compensation and super-resolution reconstruction. In the encoder, the super-resolution reconstructed image is subtracted from the original image to obtain the residual image which is compressed. In the decoder, the residual image is decompressed and added to the reconstructed image to complete the decoding process which achieves flexible rate control.

Efficient post-processing for block-based compressed video

Efficient post-processing for block-based compressed video

IEEE Region 8 International Symposium on Video/image Processing and Multimedia Communications (EURASIP)

作者： Y. Kim T. Yi School of Electrical Engineering and Computer Science Yeungnam University Gyeongsan Gyeongsangbuk South Korea

In digital video coding, the 2-D block-based discrete cosine transform (DCT) has been widely used, combined with the quantization techniques of DCT coefficients, for the purpose of compression of video data. Video compression algorithms using this block-based transform coding method cause the blocking and ringing artifacts in the reconstructed images of a video sequence. In this paper, we propose the efficient post-processing algorithm for coded video sequence, where the ringing effects near sharp edges are smoothed out and the blocking effects are removed without blurring the edge regions at the decoder. the simulation examples of processing images coded by MPEG-2 are presented to demonstrate that a significant improvement has been achieved.

We propose a digital transmission system guaranteeing both encryption and compression of multimedia data. encryption is performed via chaotic compressive sensing, while compression is ensured via latent vector transmission based on a stacked autoencoder (StAE). We demonstrated successful compression in eight cases up to a 0.03 compression ratio corresponding to 80 pixels transmitted. A compression ratio below 0.4 with StAE can achieve peak signal-to-noise ratio (PSNR) and mutual information (MI) between original and reconstructed images comparable to compression ratios between 0.6 to 0.8 without StAE, meaning same performances for about half of the pixels. Moreover, StAE can guarantee at least a 78,4% slower decrease of PSNR per pixel transmitted and at least 81.3% slower decrease of MI per pixel, averaging at 81.6% and 93.96%, respectively, for the four tested images. StAE can hence push the compression ratio of secure multimedia data while preserving the quality of the received image at receiver side.

this paper proposes a wavelet watermarking scheme for copyright protection of digital images. A secret sort is generated from the low frequency sub-band and used to improve the embedding intensity. From the experimental results, the proposed scheme is robust to withstand the wide variety of image processing attacks such as JPEG compression, scaling, cropping, and filtering attacks.

the usage of digital images in every aspect of computer and telephone application requires new means of pictures storage, compression and restoration. Such a method is presented in this article, based on discrete wavelet transformation and usage of binary sequences. During investigation, expedience of the use of structural code in the tasks of compression of data was proved. the structural signs of binary sequences of image presentations and limitations that on are laid on them are defined. the rule of determination of amount of binary sequences which form structural groups is described. Also, the rule of calculation of sequence number for binary sequence based on the amount of bit changes is described. the estimation of the expected degree of compression is done for the sequences of different length. the approach is proven to be more adjustable and preferable compared to classic algorithms of image comparison and storage.

Low power compression of EEG signals using JPEG2000

Low power compression of EEG signals using JPEG2000

引用

International conference on Pervasive Computing Technologies for Healthcare, PervasiveHealth

作者： Garry Higgins Brian Mc Ginley Martin Glavin Edward Jones Bioelectronics Research Cluster NCBES National University of Ireland Galway Galway Ireland

this paper outlines a scheme for compressing EEG signals based on the JPEG2000 image compression algorithm. Such a scheme could be used to compress signals in an ambulatory system, where low-power operation is important to conserve battery life; therefore, a high compression ratio is desirable to reduce the amount of data that needs to be transmitted. the JPEG2000 specification makes use of the wavelet transform, which can be efficiently implemented in embedded systems. the standard was broken down to its core components and adapted for use on EEG signals with additional compression steps added. Variations on the components were tested to maximize compression ratio (CR) while maintaining a low percentage root-mean-squared difference (PRD) and minimize power requirements. Initial tests indicate that the algorithm performs well in relation to other EEG compression methods proposed in the literature.
