چکیده

Product channel codes are proposed to protect progressively compressed and packetized images for noisy channels. Within packets, the product code uses the concatenation of a rate compatible punctured convolutional code and an error detecting parity check code. Across packets, Reed-Solomon codes are used. Beneets include exible choice of delay, adaptability of error protection level (i.e., unequal error protection), and scalable decoding complexity. The system outperforms the best known image coders for memoryless channels and performs well on fading channels.

Progressive image transmission applying multipath routing in mobile ad hoc networks

We investigate different allocation problem in mobile adhoc networks. The objective is to minimize the power consumption and end-to-end distortion when transmitting images. Therefore, we use progressive image coding in combination with unequal erasure protection. We investigate two different scenarios, independent packet loss events and path loss events. For both cases, the expected distortion ...

Progressive Optimal Error Protection of Embedded Codes

The embedded wavelet image coders such as SPIHT [1] or JPEG 2000 [2] allow an efficient progressive transmission of digital images. However, the bitstreams generated by these coders are very sensitive to channel noise, and error protection is necessary to ensure acceptable reconstruction fidelity. One of the most successful protection systems for embedded wavelet coders was recently proposed by...

Error Protection for Progressive Image Transmission over Memoryless and Fading Channels

A product channel code is proposed to protect progressively compressed and packetized image data that is transmitted across noisy channels. Across packets, the product code is composed of Reed-Solomon codes. Within packets, the product code uses the concatena-tion of a rate compatible punctured convolutional code and an error detecting parity check code. The beneets include exibility in terms o...

A New Unequal Error Protection Scheme for Spiht in Progressive Image Transmission

In the output of the state-of-art embedded wavelet image encoder SPHIT, three kinds of bits, namely the significance information bits, sign bits and refinement bits are interleaved, making unequal error protection(UEP) ineffective. In this work, we observed a beautiful property of SPIHT. The synchronization in decoding is of no influence if we split the original embedded bit stream into three i...
