COSC 6310 Project 1
This is an individual project. Submit a report in the Word or PDF format, with all the images inserted (embedded/pasted) in the report. Do not submit separate images.
Your grade may be partially based on the quality of the final output images. Merely performing the right procedures and steps may not guarantee a perfect score.
Part 1. (20 pts) Basics
Choose one or more digital images. Use Adobe Photoshop, or GIMP, or any other image editing software of your choice to perform all of the following functions, one at a time:
• brightness adjustment
• contrast adjustment
• nonlinear brightness adjustment (curves or levels)
• color/hue adjustment
• horizontal flip
• vertical flip
• image rotation
• affine transformation
• projective transformation
• blurring (Gaussian blur and motion blur)
In the report, for each image, paste the before and after images. Report what adjustment, processing, transformation you have done to each image with the detailed steps. It must be your own original work. If you have any questions about any specific transformation, ask me for clarification.
Part 2. (10 pts) Head Swap Using Layer Masks
Sometimes there is a need to take part of one image and blend it in another image. For example, in a family picture or a group picture, everyone looks good except one person has his eyes closed. Figure 1 is one example of a head swap in a family picture. Simple cut and paste does not work well for such situations. Layer mask is often used. The following link is a tutorial:
Find two pictures. Perform a head swap. In your report, paste the two “before” images and the “after” image, and also describe the process.

Part 3. (10 pts) Image Synthesis with Layer Masks
The same technique can be used to pull two different figures from two images and fuse them together in one image. Figure 3 is one example of the after image of such a synthesized image. Figure 4 is one of the before images. Figure 5 is another example of a synthesized image.
To Do: Find two images. Fuse them together into one image and make the synthesized image look natural. In your report, paste the two before images and the after image, and also describe the process.

Part 4. (10 pts) Remove Objects Using Clone Stamp Tool
There are times when you want to remove some objects from the image, like some distracting objects in the background. Figure 6 and Figure 7 are examples of before and after images, in which the two people are removed from the scene. The following is a link to a tutorial using clone stamp tool:
Sometimes, for small area touchup, healing brush or spot healing brush may also be used.
To Do: Find one image. Remove some objects in the scene so that the image looks better. In your report, paste the before and after image, and also describe the process.
