讲解 CMPT 401、辅导 c++设计程序
CMPT 401 – Assignment 1 (Due Oct 11th 23:59)
Instructions
You are going to submit Assignment1.cpp, Solution1.png and Solution2.png.
Fill out the functions CreateImageFromTextFile() and DiamondFilter() in
Assignment1.cpp.
Use to create Solution1.png
Use to create Solution2.png
Question 1
The pixel values of a 299-by-299 RGBA image is stored in pixels.txt in a row-major, interleaved order. Write a function CreateImageFromTextFile() to create a PNG image using these values. Save the output image as Solution1.png.
Question 2
Write a function DiamondFilter() to apply the “diamond filter” (shown below) on a grayscale version of dog.jpg. Padded the image border using cv::BORDER_DEFAULT. Save the output image as Soution2.png.
Note: remember to normalize the output pixel values with the total kernel weight.
Note: if you are using two for-loops to calculate the output pixel values one-by-one, some of the values will not be integers. In such case, apply rounding before you write the values into the output byte array.
