Real-Time Memory-Adaptive Image Compression for Resource-Constrained SystemsAdd to your list(s) Download to your calendar using vCal
If you have a question about this talk, please contact Grigorios Mingas. Current image compression techniques, despite being widespread, contain a number of assumptions that make them ill-suited for certain applications. One of these assumptions generates problems in memory-constrained situations. More specifically, the output generated by a compression algorithm does not have to deal with changing memory constraints _after_ it has been encoded. This talk examines the use of Principal Component Analysis (PCA) as a method for real-time memory-adaptive image compression. The aim of this system is to explore the trade-off of memory usage and quality of the output when the amount of data to be processed is unknown. To adapt to changing memory conditions, the system must have a method to efficiently reduce the amount of memory it takes to store a given image and do this in an on-line fashion. By freeing memory as limits are reached, it allows for a graceful degradation of quality over time while still maintaining useful output. This talk is part of the CAS Talks series.
