Mobile Phone Book Finder

Motivation:

 When people are looking for a book in the library, the call number provided by the library catalog system can easily lead them to the correct bookshelf. However, people may have to spend a very long time to find the exact position of the book on that shelf. Not only do patrons not know what the binding looks like, but books are often reshelved incorrectly and make finding the book a hassle. Our group is proposing to create a mobile phone book finder which can find the book’s position by taking a picture of the shelf and knowing the image of the book spine from a database, point out on the phone where the desired book is located on the shelf.

Implementation:

 Determining the correct position of the desired book from the shelf picture would require accurate segmentation of the books, as well as a matching algorithm of the book in order to output the most likely position of the book. The photo of bookshelf would be subject to several environmental conditions, such as lighting, reflection, rotation, scaling, among others. Such external factors will reduce the accuracy in the detection of the shape features, such as the ratio of height and width of the spines. Our algorithm may need to exploit the concept of maximally stable extremal regions to help with image segmentation. In addition, our project will also involve working with chromatic image since the colors are an important feature required for matching and recognition. We are going to implement the image processing and book matching algorithms in MATLAB with real pictures taken by Android phone. Then we will decide whether to run them on the server or directly on the mobile phone depending on the computational power required by the program. We will create our catalog database manually by using the phone to take pictures of the book spines.

Light Field Images for Background Removal

Light Field Images for Background Removal OUTPUT OVERVIEW Standard edge detection or foreground/background separation techniques, such as Otzu’smethod, require color or intensity differences between the background and regions that need tobe separated. For example, green screens are routinely set up as the background in a scene so thatthere is a clear difference in color between the background and foreground.Light filed images, captured in 4D and passively containing depth information for thescene can be used to approximate this effect. Depth estimation in the scene alone could provide a metric to separate the foreground and background, but more sophisticated methods are available.Considering the edge detection from a single image from a single viewpoint and analyzing the depths from the light field around the edges in that image, occluded edges and intensity or color edges can be distinguished. Along with the rest of the depth information this can allow the foreground and b

Using Image Processing to Identify and Score Darts thrown into a Dartboard

✔️Using Image Processing to Identify and Score Darts thrown into a Dartboard ✔️Introduction The game of darts is a throwing sport in which participants toss projectiles into a circular target  attached to a vertical surface. The target is divided into many regions which correspond to different point and multiplier values. Darts is commonly played across North America and Europe and is a popular past time for many so an application that allows players to more conveniently keep score would be widely  beneficial. “Darts” is a general term for a targeting game following this basic premise and many game variations exist within this archetype; all utilizing the standard dart projectiles with a regulation dart board. Each game variant may have different objectives for which players to aim but identifying the region in  which the dart has hit in the dartboard is necessary for proper scoring. This project proposes the use of image processing to identify thrown darts and to det

Digital Make up Face Generation

Digital Make up Face Generation Goal Current make-up applications rely on using photoshop tools to apply makeup on the target's digital  faces and generate results. While these applications allow customization, a customer who wants to  quickly decide on the type of makeup kit to buy at a store will not find it useful. The customer might just  want to find out how the make-up look on the cover or billboard will look like on her face. The goal of  this project is to use an existing reference image of another subject with a make-up applied, and  transfer the reference's make up on the target's face. The application can be further extended to photo  retouching and illumination transfer from the reference image to the target. Methodology In order to transfer the make-up from the reference onto target in a pixel by pixel basis, the areas of  interest must align. Face features such as eyes, nose, mouth and contours of the face, will be recognized  using Active Shape
