Dynamic Approximation of JPEG Hardware
JPEG compression based on the discrete cosine transform (DCT) is a key building block in low-power multimedia applications. Approximate computation techniques are used to exploit the error tolerance of JPEG. An image-dependent framework is proposed in this work to design optimized approximate hardware with variable approximate bit-widths for a userspecified error budget. The proposed method can...
متن کاملApplication of M-JPEG compression hardware to dynamic stimulus production.
Inexpensive circuit boards have appeared on the market which transform a normal micro-computer's disk drive into a video disk capable of playing extended video sequences in real time. This technology enables the performance of experiments which were previously impossible, or at least prohibitively expensive. The new technology achieves this capability using special-purpose hardware to compress ...
متن کاملBenchmarking and hardware implementation of JPEG-LS
The JPEG-LS algorithm is one of the recently designated standards for lossless compression of grayscale and color images. In this paper, simulation results for lossless and near lossless compression of various image types are presented in order to explore the algorithm’s effectiveness for a number of applications. A hardware implementation using VHDL is proposed and the schematic of a JPEG-LS c...
متن کاملHardware / Software co - design for JPEG 2000
For demanding applications, for example image or video processing, there may be computations that aren’t very suitable for digital signal processors. While a DSP processor is appropriate for some tasks, the instruction set could be extended in order to achieve higher performance for the tasks that such a processor normally isn’t actually design for. The platform used in this project is flexible...
متن کاملdynamic coloring of graph
در این پایان نامه رنگ آمیزی دینامیکی یک گراف را بیان و مطالعه می کنیم. یک –kرنگ آمیزی سره ی رأسی گراف g را رنگ آمیزی دینامیکی می نامند اگر در همسایه های هر رأس v?v(g) با درجه ی حداقل 2، حداقل 2 رنگ متفاوت ظاهر شوند. کوچکترین عدد صحیح k، به طوری که g دارای –kرنگ آمیزی دینامیکی باشد را عدد رنگی دینامیکی g می نامند و آنرا با نماد ?_2 (g) نمایش می دهند. مونت گمری حدس زده است که تمام گراف های منتظم ...
