A fast image decoder 20 for decoding a compressed image encoded using the Poisson picture processing algorithm is disclosed. The invention includes a run length decoder 23 for run length decoding the compressed image, a processing circuit including a lookup table 24 for iteratively processing each pixel output by the run length decoder 23, a frame memory 26 for storing the reconstructed image and a feedback path 28 for providing image data from the frame memory 26 to the lookup table 24 for successive processing iterations. The reconstructed image from the frame memory 26 may be viewed on a display or further processed as required by the specific application.

Fast image decoder

A system for washing the air in a coastal environment in which a volume of air moves from a land mass to a water mass. The system includes a plurality of fountains 12 mounted offshore which spray a volume of water into the path of the air flow. Water is stored under pressure and selectively released to form the spray. In specific embodiments, wave motion is used to provide the power to pressurize the stored water. Wave power is extracted by dual reciprocating pumps 50 and 51 connected to a float 40. Wave power is amplified by lenses 20 which focus the waves onto the floats 40. A control system 100 senses pollution and controls the generation of the spray. In addition, wave motion is sensed and used to control the position of the lens 20 for optimum performance and minimum wear.
