MIPS Assembly language

Your task is to write the body of the threshold function that takes in an array of pixels of a grayscale image (one byte per pixel) along with its dimensions and applies binary thresholding. The input image for this part is a square sized grayscale image. For grayscale images, one byte is used to represent each pixels intensity where the possible values range from 0x00 to 0xFF. In other words, the image is stored in a 2D array where each element is a byte.
