Matlab Image Processing Exercises

1. Download the sample image

2. Read the image into Matlab. (im_0)

3. Display the image.

4. Convert im_0 into grayscale and display the grayscale image in a separate window. (im_1)

5. Resize im_0 into half of its original size (half in the x and y direction). (im_2)

6. Resize im_0 by setting 64 pixels in one direction. Keep the aspect ratio of the image. (im_3)

7. Use the ginput command to get the coordinates of a rectangular box in the image for object selection. For example, select the animal in the sample image.

8. Extract the rectangular sub-image and display the sub-image in a separate window. (sub_0)

9. Resize the sub-image into half of its original size, and then paste this smaller sub-image (sub_1) into the original image (im_0) to a place you define. You can paste a series of sub-images, such as size (sub_2), 1/8 size (sub_3) of the sub-image, into different locations in the original image (im_0).

10. Save the final image as your version of animal hybrids.
