Low complexity energy efficient very low bit-rate image compression scheme for wireless sensor network
A simple, fast, low complexity image transform and coding algorithm is proposed. Specifically designed for low power, resource constrained devices. Experimental results are simulated with ATmega128 processor (8 MHz) of Mica2 mote to find the computation time and computation energy. The proposed method is extremely fast and consumes only 4% of computation energy needed by JPEG compression. Relevant comparisons with relevant solutions are provided.
