Facial Expression Recognition
Facial Expression Recognition System - Matlab source code
We propose an algorithm for facial expression recognition which can classify the given image into one of the seven basic facial expression categories (happiness, sadness, fear, surprise, anger, disgust and neutral). PCA is used for dimensionality reduction in input data while retaining those characteristics of the data set that contribute most to its variance, by keeping lower-order principal components and ignoring higher-order ones. -

Automatic 3D Coordinate Points Generator
The project aims at generating 3D coordinates from a set of 2D images
...The entire project is based on the principles of Photogrammetry. The subject of interest is embedded with patterns of retro-reflective dots. The reason that these dots were attached is that they appear very bright in the image if it is captured using flash. An auto-bar is used to define the coordinate system reference. The algorithm which performs this transformation is broken down to several steps. First step is converting the images to grayscale. Then detecting the retro-reflective dots by the “Polygon” approach. Same dots in different images were matched by Pattern Matching algorithm. ... -

...Usually in an SMC framework there is a natural ordering of the states of the samples. The order typically depends on observations about the states or on the annealing setup used. In many applications (e.g., image jigsaw puzzle problems), all observations (e.g., puzzle pieces) are given at once and it is hard to define a natural ordering. Therefore, we relax the assumption of having ordered observations about states and propose a novel SMC algorithm for obtaining maximum a posteriori (MAP) estimate of a high-dimensional posterior distribution.

Octree Method For Particles
simulation of particles using an oct-tree
...the low-level "octets" can be distributed among a cluster of computers, organized in a grid. they don't have to send each other their whole dataset - only a zoomed out image of it. the further away, the more zoomed out. thus, i/o traffic is greatly reduced. combine this with the fact that it's an O(N) algorithm, and what you get is an accurate particle-based physics simulator whose simulation speed scales with the number of particles per compute unit even for VERY large particle counts and VERY large computing arrays. ... -

PanGP
PanGP is a tool for quickly analyzing bacterial pan-genome profile.
PanGP is a tool for quickly analyzing bacterial pan-genome profile. It has integrated two kinds of sample algorithm, so that it could calculate the pan-genome profile of a population with dozens of or hundreds of strains at extremely low time-cost. At the same time, a user-friendly graphical interface was designed and the image about pan-genome profile could be drawn by PanGP directly. -

Face Recognition Based Login Assistant
Login to Websites Automatically Using Your Face as Password
...In face localization, the task is to find the locations and sizes of a known number of faces (usually one). In face detection, one does not have this additional information. Face detection is mostly used along with facial recognition feature to extract faces out of an image or video feed and identify the faces against a set of stored images. This feature can be used for tracking prisoners, attendance and signing in to user accounts. The Viola - Jones Algorithm presents a novel face detection technique, we would implement this technique for face detection and then use eigen faces method to recognize the person in the image. ... -

LAVA for AFM
Lloyd's Algorithm-based Volumetric Analysis for AFM Images
This MATLAB-based program enables analysis of AFM images. In particular, it allows the user to measure the volume of all distinguishable features in an image and to isolate and sort those particles. As the name implies, LAVA uses Lloyd's Algorithm, also known as k-means sorting, to identify a small set of volumes representative of the actual distribution of particle in the image. Although developed for determining feature volume, LAVA is also completely compatible with other types of image analysis, such as fluorescence intensity. ... -

Client Side Login Authentication Helper
The project is to do pre-check of password before sending to server
...The purpose of the project is to capture and address unintentional human errors that could be resolved at the client side during the login process. Solution Abstract: An array of images are loaded at the client side. One of the images is displayed for every password entered based on a simple algorithm. The image is computed based on the password and hence it will change only when the user changes his password. Hence, the displayed image will become familiar to the user until he changes the password. It helps the user understand whether he input the right password before sending it to the server. This would be of great help in highly busy servers like stock-market and bandwidth challenged networks such as mobile data networks and dial-up networks.
