Multiresolution coding of motion capture data for real-time multimedia applications
In this work, we present a novel and efficient method for coding of motion capture (MoCap) data obtained from recording of human actions. MoCap data is represented as hierarchies of joints and parameterized by...

An adaptive cartoon-like stylization for color video in real time
The cartoon-like stylization of color video images is one of the major types of non-photorealistic rendering. It has broad applications in the entertainment industry due to its lively style, flexible form, and...

Latent overlapped fingerprint separation: a review
Fingerprint matching is a widely used process to aid in crime scene investigation, where fingerprint fragments are often found on objects and surfaces. In such cases, the lifted fingerprints (called latents) are ...

Perception-based adaptive quantization for transform-domain Wyner-Ziv video coding
Distributed video coding (DVC) is desirable for encoding systems with tight power or computational constraints, for which the popular practical solution is transform-domain Wyner-Ziv video coding (TD-WZVC). To...

Extracting watermarks from printouts captured with wide angles using computational photography
Thus far the research of print-cam robust watermarking methods has focused on finding new methods for embedding and extracting the watermark. However, the capturing process itself, has been neglected in scient...

Metadata hiding for UAV video based on digital watermarking in DWT transform
As the advent of the Unmanned Aerial Vehicles (UAVs) has been increased, the protection of the information within the transmitted or stored video has become a big challenge. Most known drone systems attach met...

A new image encryption using color scrambling based on chaotic permutation multiple circular shrinking and expanding
In this paper, we propose a new color image encryption method using color scrambling based on the chaotic permutation multiple circular shrinking and expanding (CPMCS/ CPMCE). The plain color image with a size...

Arbitrarily-oriented multi-lingual text detection in video
Text detection in arbitrarily-oriented multi-lingual video is an emerging area of research because it plays a vital role for developing real-time indexing and retrieval systems. In this paper, we propose to ex...

Text image super resolution using within-scale repetition of characters and strokes
In text images, there are some frequently used characters repeating more than others. Likewise, some characters have common strokes. This characteristic is used in this paper for machine-printed text-image sup...

Subjective MOS model and simplified E-model enhancement for Skype associated with packet loss effects: a case using conversation-like tests with Thai users
This paper proposes two mathematical models that can be used to estimate VoIP quality from Skype, which is one of the most popular VoIP applications. The first model is simple, it has been developed using data...

Blind watermarking algorithm based on spiral scanning method and error-correcting codes
This work is a connecting link between the field of digital transmission and (3 Dimension) 3D watermarking. In fact, we propose in this paper a blind and robust watermarking algorithm for 3D multiresolution me...
