High efficiency video coding (HEVC) standard achieves half bit-rate reduction while keeping
the same quality compared with AVC. However, it still cannot satisfy the demand of higher …

This letter presents two adaptive interpolation methods based on applying an inverse
gradient to conventional bilinear and bicubic interpolation. In simulations, the proposed …

Electrocardiograph (ECG) compression techniques are gaining momentum due to the huge
database requirements and wide band communication channels needed to maintain high …

In this paper, we propose an image tampering localization algorithm using semi-fragile
watermarking and Error-Locating codes in the DWT domain. By introducing different families …

Emerging evidence suggests that respiratory frequency (fR) is a valid marker of physical
effort. This has stimulated interest in developing devices that allow athletes and exercise …

Glaucoma is a dangerous eye disease and it affects the vision in people. It mainly damages
the eye nerves and the severe cause of glaucoma leads to permanent sight loss. The target …

The fight against cancer, a relentless global health crisis, emphasizes the urgency for
efficient and automated early detection methods. To address this critical need, this review …

A new class of related algorithms for deblocking block-transform compressed images and
video sequences is proposed in this paper. The algorithms apply weighted sums on pixel …

We study the problem of video shot boundary detection using an adaptive edge-oriented
framework. Our approach is distinct in its use of multiple multilevel features in the required …

In this paper, a set of techniques used for downsampling and upsampling of 2D images is
analyzed on various image datasets. The comparison takes into account a significant …
