Robust and efficient video/image transmission
… has become a primary medium for information transmission. The unreliability of channel conditions, limited channel bandwidth and explosive growth of information transmission requests, however, hinder its further development. Hence, research on robust and efficient delivery of video/image …

Joint source channel coding for progressive image transmission
Recent wavelet-based image compression algorithms achieve best ever performances with fully embedded bit streams. However, those embedded bit streams are very sensitive to channel noise and protections from channel coding are necessary. Typical error correcting capability of channel codes varies …

A high speed image transmission system for ultra-wideband wireless links
… that offers short range, high data rate wireless transmission, with low power consumption and low consumer cost. Operating in the 3.1 GHz - 10.6 GHz frequency band with bandwidth above 500 MHz, it is an overlay technology that can co-exist with other narrowband services in the same frequency …

Techniques in image restoration and enhancement
Image processing in its broad sense pervades many areas but it is convenient to group it into three main sections, viz: image coding, usually for image transmission over telecommunication links; pattern recognition for detecting the presence of a particular distribution in an image which is …

Mcmc- Based Optimization And Application
… optimization problems. The first problem is image transmission over varying channels. Existing work in media transmission generally assumes that channel condition is stationary. However, communication channels are often varying with time in practice. Adaptive design needs frequent feedback …

Recognition of 3D compressed images and its traffic monitoring applications
… These systems must manage large numbers of images sent over communication networks. For example, a high transmission load results when security cameras continuously transmit images. Operators are bored and fatigued from viewing cycled images on a few monitors. In this thesis, we present a …

Development of a Low-Cost System for Monitoring Root Growth Dynamics
… offer a non-invasive solution for capturing root images over time. However, existing products are typically expensive or manually operated. These limitations restrict access to dynamic root data, particularly for small-scale research. The solution presented in this study bridges this gap through …
