چکیده

An image enhancement algorithm for low-vision television viewing was developed. The algorithm enhances the images in the JPEG/MPEG domain by weighting the quantization table. The advantages of our algorithm are threefold: (1) Low computation (only a change of the 8× 8 quantization table in the decoding stage); (2) Suitable for real–time application; and (3) easily manipulated by individual users, because the enhancement level can be controlled at the receiver.

Visual search performance of patients with vision impairment: effect of JPEG image enhancement.

PURPOSE To measure natural image search performance in patients with central vision impairment. To evaluate the performance effect for a JPEG based image enhancement technique using the visual search task. METHODS One hundred and fifty JPEG images were presented on a touch screen monitor in either an enhanced or original version to 19 patients (visual acuity 0.4-1.2 logMAR, 6/15 to 6/90, 20/5...

A Contrast Enhancement Framework with JPEG Artifacts Suppression

Contrast enhancement is used for many algorithms in computer vision. It is applied either explicitly, such as histogram equalization and tone-curve manipulation, or implicitly via methods that deal with degradation from physical phenomena such as haze, fog or underwater imaging. While contrast enhancement boosts the image appearance, it can unintentionally boost unsightly image artifacts, espec...

A Modified Digital Image Watermarking Scheme Based on Nonnegative Matrix Factorization

This paper presents a modified digital image watermarking method based on nonnegative matrix factorization. Firstly, host image is factorized to the product of three nonnegative matrices. Then, the centric matrix is transferred to discrete cosine transform domain. Watermark is embedded in low frequency band of this matrix and next, the reverse of the transform is computed. Finally, watermarked ...
