Abstract: This research introduces efficient algorithms for the forward and inverse lossless Integer-to-Integer Tchebichef Transform (I2ITT), tailored for resource-constrained embedded systems. These algorithms are then implemented on FPGA using fixed-point arithmetic for lossless image reconstruction. The… read more here.
