Visible Distortion Predictors Based on Visual Attention in Color Images

Autor: Jae-Jeong Hwang, Sang-Gyu Cho, Nae-Joung Kwak

Publikováno v: Journal of information and communication convergence engineering. 10:300-306

An image attention model and its application to image quality assessment are discussed in this paper. The attention model is based on rarity quantification, which is related to self-information to attract the attention in an image. It is relatively s

Study on the Damage Characteristics Under the High-Velocity Impact of Composite Laminates Using Various Sensor Signals

Autor: In-Gul Kim, Sang-Gyu Cho, Seokje Lee, Won-Young You

Publikováno v: Journal of The Korean Society for Composite Materials. 24:49-55

The use of advanced composite materials in main structures of military and civil aircraft has been increased rapidly because of their considerable metals in high specific strength and stiffness. However, the mechanical properties of composite materia

Maritime Object Segmentation and Tracking by using Radar and Visual Camera Integration

Autor: Jae-Jeong Hwang, Sang-Hyon Park, Sang-Gyu Cho, Jung-Sik Lee

Publikováno v: Journal of information and communication convergence engineering. 8:466-471

We have proposed a method to detect and track moving ships using position from Radar and image processor. Real-time segmentation of moving regions in image sequences is a fundamental step in the radar-camera integrated system. Algorithms for segmenta

Real-time pupil detection based on three-step hierarchy

Autor: Sang-Gyu Cho, Kyung-Sik Jin, Jung-Sik Lee, Jae-Jeong Hwang

Publikováno v: Proceedings 7th International Conference on Signal Processing, 2004. Proceedings. ICSP '04. 2004..

A real-time pupil detection' system that detects the pupil movement from the real-time video data achieved by the visual light camera for general purpose personal computer is proposed. It is implemented with three steps; at first, face region is dete

Human eye interfaced segmentation and multiple video object coding

Autor: Jae-Jeong Hwang, Sang-Gyu Cho, Hong Ren Wu, Chi-Gyu Hwang

Publikováno v: VCIP

In the general multiple video object coder, more interesting objects such as a speaker or a moving object is consistently coded with higher priority. Since the priority of each object may not be fixed in the whole sequence and be variable on a frame
