In this paper, we propose systems which can render free viewpoint images by using depth image based rendering for live video communications. Experimental results show that an image and depth transmission system is more suitable than an all multi view transmission and an only free viewpoint image transmission system. Especially in the image and depth transmission system, transmitting two images ...

Communication has to be secure in order to be kept private. The latest developments in the field of digital communication have made secret communication possible. Image hiding is a method in which a secret image is hidden in a cover image thereby forming a hybrid or stego image. In this paper, data hiding is performed by taking difference value of three and two neighbouring pixels by adapting Z...

Contemporary picture archiving and communication systems are limited in managing large and varied image collections, because content-based image retrieval (CBIR) methods are unavailable. In this paper, an XML-based data and resource exchange framework is defined using open standards and software to enable specialized CBIR systems to act as geographically distributed toolkits. The approach enabl...

Scalable Image Communication is useful in multiuser heterogenous environments. In this project, we plan to implement an unequal error protection method for Embedded Foveation Image Coding (EFIC) compressed images, using rate compatible punctured turbo codes. Different portions of the bitstream are protected unequally, based on the importance of data to the end receiver, i.e, human eye. Our prim...

Among other factors that characterize satellite communication channels is their high bit error rate. We present a system for still image transmission over noisy satellite channels. The system couples image compression together with error control codes to improve the received image quality while maintaining its bandwidth requirements. The proposed system is tested using a high resolution satelli...

This study describes intelligent transport image sensor communication (ITS-ISC) systems that use LED arrays as transmitters imitate traffic lights. Three signal-transmission schemes -luminance modulation, spatial and combined luminance modulation- array. However, their suitability for ITS-ISC has not been explored yet. Therefore, we compare the performance of these three under strong saturation...
