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. -

HIPAcc
Heterogeneous Image Processing Acceleration (HIPACC) Framework
HIPAcc development has moved to github: https://github.com/hipacc HIPAcc allows to design image processing kernels and algorithms in a domain-specific language (DSL). From this high-level description, low-level target code for GPU accelerators is generated using source-to-source translation. As back ends, the framework supports CUDA, OpenCL, and Renderscript. HIPAcc allows programmers to develop imaging applications while providing high productivity, flexibility and portability as well as competitive performance: the same algorithm description serves as basis for targeting different GPU accelerators and low-level languages. -

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. ... -

Ofeli (as an acronym for Open, Fast and Efficient Level set Implementation) demonstrates how to operate an image segmentation algorithm of Y. Shi and W. C. Karl |1|, using a discrete approach for the approximation of level-set based curve evolution (implicit active contours). This is a novel (2005) and fast algorithm without the need of solving partial differential equations (PDE) while preserving the advantages of level set methods, such as the automatic handling of topological changes. ...

Hierarchical Image Segmentation
A hierarchical image segmentation is a set of several image segmentations at different levels of segmentation detail in which the segmentations at coarser levels of detail can be produced from simple merges of regions from segmentations at finer levels of detail. A unique feature of hierarchical image segmentation is the the segmented region boundaries are maintained at the full image spatial resolution at all levels of segmentation detail in the hierarchy. ... -

segment
Solve the Viterbi algorithm in a data stream
It is often necessary to assign a series of discrete values to continuosly variable data sequenced by time, position, etc., thereby parsing the data into fewer and larger segments of variable width. The 'segment' utility takes an input data stream as a Hidden Markov Model and applies the Viterbi algorithm to find the most likely segmentation path through the data. -

smooth
Wavelet smoothing in a data stream
It is often necessary to smooth high frequency fluctuations out of data streams sequenced by time, position, etc. The 'smooth' utility applies such smoothing using the wavelet algorithm. This implementation of wavelet smoothing was optimized for use in a data stream. It was adapted from HMMSeg Wavelet.Java by Thomas E. Wilson, University of Michigan. HMMSeg Wavelet.Java was written by Andrew Hemmaplardh, University of Washington. http://noble.gs.washington.edu/proj/hmmseg/ Unsupervised segmentation of continuous genomic data, Bioinformatics 2007 23:1424-1426 See the above references for a more thorough description of the principles behind wavelet smoothing. -

graphseg
Library for segmenting a graph, images in particular.
Primarily this library was developed for producing a set of super-pixels from an image (i.e. an over-segmentation). The segmentation is produced by running multiple instances of Dijkstra's Algorithm from a set of seed points; those nodes which belong to a given Dijkstra cloud form a segment (so the number of segments is fixed and determined at the beginning of the algorithm). The goal is to add code that moves from the over-segmentation to a more useful segmentation. -

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. -

im2ascii
Image to ASCII converter that takes character shape into account
im2ascii is a small python script that converts images to ascii-art. Unlike common ascii-art generators, it does not only use each character's mean brightness, but matches the full character shape. Pro: Better ascii-art quality (see screenshots for examples) Con: Matching is very resource intensive Dependencies: Python 2.7, PIL, numpy, scipy -

SURF-nanodots
Very basic computer vision program
...Originated in summer 2007 as a collection of C compiled for Matlab (MEX) files and was eventually ported to a standalone C++ application with a GUI created in Qt. This program takes atomic and magnetic force microscope (AFM/MFM) image pairs as input and uses threshold segmentation to identify magnetic nanodots by intensity in the AFM image. These are then used to assess the magnetic states of those dots in the MFM image Attribution: "C++ GUI Programming with Qt 4" by Blanchette and Summerfield was helpful in getting me started on the GUI. -

BLIMToolbox
A set of tools for processing Argus images of the nearshore zone.
BLIM Toolbox is a collection of tools for the extraction and analysis of visual features in Argus images of the nearshore zone. The toolbox provides an implementation of the BarLine Intensity Mapper (BLIM) algorithm, which extracts high-intensity bands from Argus images. Also, several analysis and export functions are included in this toolbox, such as timestack plots and movies. The main incentive for the development of this toolbox was reducing the amount of time and effort a user spends on image analysis. This is achieved by a user-friendly graphical interface, functionality for browsing through images and results, flexible import and export functions, and the possibility to add user interface components and additional implementations of algorithms. ... -
