Hello...please i need this in MATLAB

Problem: Download a gray scale image "Lena", implement the uniform quantization method. For the original image, the quantization level L = 256. Implement uniform quantization with level L = 32, q . Implement uniform quantization with level L- 16, q -s Plot the resulting image - 16. Plot the resulting image 4, q 64. Plot the resulting image Implement uniform quantization with level L Problem: Download a gray scale image "Lena", implement the uniform quantization method.
