Optical Verification of Mouse Event Accuracy

 OUTPUT


Motivation:

 The project is designed to address the issue of fair gameplay in professional competitive gaming events comparing point tracking techniques, assessing optical flow, and multi-object tracking. In doing so, we aim to analyze and determine the most robust system for accurately correlating mouse movements against their corresponding motion on the player’s screen. By cross referencing these data points, we will be able to
confirm the validity of a player’s movement during a gaming event. Proposal Optical verification of mouse events will track mouse accuracy by analyzing a marker on the mouse and comparing, in real time, mouse movement to the resulting movement on screen. We will add multiple visual markers on the mouse and then perform feature
extraction techniques to find their position and calculate the displacement vector between frames. We will compare multiple algorithms to ensure consistency in the displacement vector for all features. We will try markers of various shapes such as box and circle and compare which algorithm performs best in various lighting conditions. apply a template and find a local centroid at each frame of the video. To track the change in the X Y coordinate space, we will find the dy/dx change between consecutive video frames and record the data with the values reported by a mouse event. In order to visualize the accuracy, we will display a mouse pointer trace showing the path reported by the optical verification method and the mouse event values. To simulate alteration of mouse event values, we will provide a deterministic software solution that allows the user to introduce alteration of the mouse event at will. 

 Implementation:

 Android device for video capture and image processing, Laptop for viewing mouse trace, accuracy, and tamper reporting.

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
