 Sign Language Recognition on Android

Project Idea and Goals

For our project, we would like to develop an algorithm for human hand detection and in-terpretation. This means that we not only want to identify human hands in images, but also correctly model their pose and classify gestures. Although this algorithm has many varied applications such as human-machine interface commands or machine understanding of human behavior, we will use this algorithm specifically to detect and interpret American Sign Language gestures.

Specific goals for the project include (1) live video detection and conversion of sign language to text in real time and (2) mobile implementation on an Android device.

Proposed Methodology

In order to do this idea justice, we plan to organize the project into an image processing component for hand segmentation and modeling of the gesture (for EE 368), and a machine learning component for hand pose interpretation (for CS 229). We would like the image processing component of this project to detect both the position and configuration of human hands. This will make the overall algorithm more robust in terms of the camera angle,lighting conditions, etc.
The first step should be a form of segmentation that can identify human skin tones/ hand geometry. We then intend to include some redundant measures of identifying hands, in order to counter scenarios in which one method might fail to pick up the presence of a hand. We have already identified potential datasets (such as this American Sign Language Lexicon Video Dataset) to use in development.
Once a region of interest has been identified as containing a hand, the last detection step would involve creating a model of the hand pose. The features extracted from this model would then be provided to the machine learning component of the project. We will initially implement this algorithm on still images, and then tackle video streams if time permits.

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 da...

Face Detection, Extraction, and Swapping on Mobile Devices

Face Detection, Extraction, and Swapping on Mobile Devices OUTPUT: DOCUMENTATION: We will use the Viola-Jones face detector in OpenCV as a starting point. Once we have found two faces we will apply some post processing to make sure that we have the entire face without any holes. Once we have a binary mask of the faces’ fully connected components, we plan to use cvBlobsLib (similar to regionprops function in Matlab) to do face region labelling and extraction. Choosing the faces to swap will either be random or done through a simple UI. Initially we will translate the faces to match the new face’s centroid with the centroid of the old face. Then, using the relative locations of features detected using OpenCV (such as the eyes, nose, and mouth) we will determine the orientation of the face in the plane parallel to the camera lens. Then, the relative sizes of these features will allow us to determine the degree of rotation away from the camera. However, if the faces we ar...
