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.

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.
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");

The discrete cosine transform (DCT) represents an image as a sum of sinusoids of varying magnitudes and frequencies. The dct2 function computes the two-dimensional discrete cosine transform (DCT) of an image. The DCT has the property that, for a typical image, most of the visually significant information about the image is concentrated in just ...
