Project 4 Scalar Quantization

1), The pixel values in the Sena image are not really distributed uniformly. Obtain a histogram of the image. what kind of distribution it looks like?

2), Applying 1-,2-,3-bit uniform quantizer to the Sena image. Compute the mse of the uniformed quantized image and show the quantized image.

3), Design 1-,2-,3-bit quantizer for the Sena image, which can match the distribution  better than a simple uniform quantizer. Compute the mse of the quantized image and show the quantized image.
