This weekly report outlines a formula to obtain the exact number of each type (A-K) based on the width and height of an image. It explains that the formula calculates the number of pixels by iterating through the width and height, increasing each by a set difference (Dw and Dh) that varies for each type. It provides Dw and Dh values for each type and gives an example of applying the formula to Type A. The report concludes by discussing transposing the image to calculate the integral image by column-major instead of row-major.
