Image coding using self-supervised backpropagation neural network

Image data compression is implemented using a self-supervised backpropagation neural network. First, a backpropagation discrete cosine transform (BPDCT) is developed and then used for transform coding. Secondly, to alleviate edge distortion, classification techniques are applied to transform image coding. The classification technique is based on edge detection since the human visual system is more sensitive to edges. Simulation results show that the BPDCT works better for image coding than a truncated DCT. Classification techniques improve the performance of the BPDCT
