چکیده

In this paper, we explore the technique of colorization for video compression. The chrominance of the intermediate frames is discarded during encoding. At the time of decoding, chrominance values, which are dropped, are approximated from colorizing grayscale frames by transferring color from a source color frame to a targeted grayscale frame. So far human intervention is an integral part of colorization and pseudo colorization. But the present work can be looked upon as a novel application of the color transformation methodology without any human intervention for video compression. The videos regenerated at the decoding end demonstrate the potential and the utility of color transferring techniques in video compression domain.

Color Transfer Using Motion Estimations and Its Application to Video Compression

In this paper a novel scheme for colored video compression using color transfer techniques is proposed. Color transfer for video sequences is made more accurate by incorporation of motion information in the transfer mechanism. Encoder and decoder architectures for the proposed compression scheme are also presented. Compression is achieved by firstly discarding chrominance information for all bu...

A New Unequal Error Protection Technique Based on the Mutual Information of the MPEG-4 Video Frames over Wireless Networks

The performance of video transmission over wireless channels is limited by the channel noise. Thus many error resilience tools have been incorporated into the MPEG-4 video compression method. In addition to these tools, the unequal error protection (UEP) technique has been proposed to protect the different parts in an MPEG-4 video packet with different channel coding rates based on the rate...

A New Hybrid Method for Colored Image Steganography Based On DWT

Data transmission security has become an extremely important field of research. Steganography is an art of hiding information in image, audio and video files in a way that would meet the security requirements in the form of overt or covert. In this study, we propose a new hybrid steganography technique for color images that hide secret messages in the frequency domain of a cover image's blu...

GONG, FINLAYSON, FISHER: RECODING COLOR TRANSFER AS A COLOR HOMOGRAPHY1 Recoding Color Transfer as a Color Homography

Color transfer is an image editing process that adjusts the colors of a picture to match a target picture’s color theme. A natural color transfer not only matches the color styles but also prevents after-transfer artifacts due to image compression, noise, and gradient smoothness change. The recently discovered color homography theorem proves that colors across a change in photometric viewing co...
