When reading the image file with imread, you can orient the image data automatically according to this orientation tag by specifying the AutoOrient name-value argument as true. Make a tiling of eight versions of the same image with different values in their Exif Orientation tags. The file clock_ n.jpg has a value of n in its Exif Orientation tag.
Step 4: Write the Adjusted Image to a File. Write the newly adjusted image I2 to a file using the imwrite function. This example includes the extension ".png" in the filename, so the imwrite function writes the image to a file in Portable Network Graphics (PNG) format. You can specify other file formats. imwrite(I2, "pout2.png");

Description. I = rgb2gray(RGB) converts the truecolor image RGB to the grayscale image I. The rgb2gray function converts RGB images to grayscale by eliminating the hue and saturation information while retaining the luminance. If you have Parallel Computing Toolbox™ installed, rgb2gray can perform this conversion on a GPU. example.
