WebThe graythresh function in MATLAB is used to determine the threshold level for a grayscale image, but it cannot be used directly on an indexed image. To use graythresh on an indexed image, you need to first convert the indexed image to a grayscale image. Here's an example of how to use graythresh on an indexed image in MATLAB: WebNov 28, 2024 · How do I do this for each frame of a video and have matlab give me launch angle and velocties in the x and y directions?
