-First, the curriculum design topic: The C/C++ Languages gray image coding procedures Hoffman Second, design the content and requirements: 1, with C/C++ Language to complete the design, debugging a computer program　2, on machine hours: 8 hours　3, the results are listed in the design and submitted the report of the curriculum design. Third, design methods and steps: 1, Statistics 1 BMP format the probability of gray-scale images, and displays the corresponding gray-scale value and probability　2, of this image do Huffman code　and lists the results of coding. 3, calculation of the average code length and entropy values, calculate the coding efficiency. 4, all results have called displayed.
