Part 1: I do not understand why my program isn't working. It gives me a purple image. I chose anything

I = imread('hidden01.png');

newI = (I

Part 1: Flattening the Images There is an image dog.png, which you will be concealing at least 10 hidden images in. Try viewing it with . 1. 2. There are ten images labeled hiddenXXpng with XX from 1 to 10. Let's take the grayscale hidden image and make it black and white: a. Load one of the hidden images. It should be in a 400x400 integers matrix (grayscale). b. Create a function to "Flatten" the image by creating a 400x400 matrix with values "1" if the corresponding hidden image pixel is dark and "O" if the pixel is light (black&white) Your threshold for dark/light is up to you as long as the image is still distinguishable after converting from grayscale to black&white Create a function to "Expand" the flattened image by taking the 400x400 flattened image and creating a new RGB image with black pixels for "1" elements, and white pixels for "O" elements Test by Flattening and Expanding one of the images and making sure it can be displayed properly with the simage> command. c. Part 2: Create Embedding Techniques As an example for one of the techniques that can be used is the odd/even embedding technique This is an example one of the different techniques that you will use to hide all the black and white images into the concealing image. The flattened hidden image is a 400x400x1 matrix of values 0 (white) and 1 (black) pixels. The normal image is a 400x400x3 matrix of values 0-255, representing the values of the red, green, and blue channels. Our first embedding technique goes as follows: 1. 2. 3. Use your "Flattening" function from part 1 to flatten the hidden image selected by the user to a flattened hidden image If flattened hidden image pixel (x.y) is black, make the red channel of pixel (x.y) in the normal image odd valued by either subtracting zero or one. If flattened hidden image pixel (x,y) is white, make pixel (x.y) on the red channel of the normal
