Abstract: This paper deals with data hiding in compressed video. Unlike data hiding in images and raw video which…
Combining Invariants for Similarity Transformation and Blurring Using Orthogonal Zernike Moments
Introduction Image recognition systems often face challenges due to geometric transformations such as rotation, scaling, translation, and image blur. These…
Super-Resolution Method for Face Recognition Using Nonlinear Mappings on Coherent Features
ABSTRACT : Low-resolution (LR) of face images significantly decreases the performance of face recognition. To address this problem, we present…
QUALITY ASSESSMENT OF DEBLOCKED IMAGES
ABSTRACT We study the efficiency of deblocking algorithms for improving visual signals degraded by blocking artifacts from compression. Rather than…
