Object-Based Unequal Error Protection

Marka, Madhavi 03 August 2002 (has links)
This thesis presents a comparison of two methods for Object-Based Unequal Error Protection. The two methods, Combined Unequal Error Protection and Individual Unequal Error Protection, add Forward Error Correcting Codes to embeddedly coded objects of an image. This is done so that each byte within an object is protected according to its importance, has object-level of error protection proportional to the object's importance to the reconstructed quality, and has random access at the receiver. It is found that random access to the objects is obtained at a cost in terms of quality.
