TrackingExample
This project presents simple marker detection and 3D augmentation
This is a project demonstrating tracking of a marker consisting of 6 blobs placed on a black palette and drawing a virtual house on it. Detection of the marker and augmentation (drawing of the house) are done in real time. Image from almost any internet camera can be used. The program is using incremental tracking, in which the position of the marker in the previous frame is used to improve the detection. The homography calculation needed for the augmentation can be performed using 4 different methods: -Direct Linear Transform, -basic OpenCV algorithm -OpenCV RANSAC based algorithm -OpenCV Least-Median based algorithm. ... -

Ncrypt
Text and image encryption and decryption software
This software provides a mean for users to encrypt and decrypt data in the form of text and images. The program follows a basic encryption algorithm that relies on mathematical properties of matrices, such as row operations, matrix multiplication, and invertible matrices . This program works by allowing the user to input a key in the form of a matrix, on which the program bases the encryption. The program then performs the encryption. The software only works in the scope of text files with a maximum of 150 characters, and image files with a maximum size of 128 x 128. -

PhyloPart
automated partition of phylogenetic trees
Understanding the determinants of virus transmission is a fundamental step for effective design of screening and intervention strategies to control viral epidemics. Phylogenetic analysis can be a valid approach for the identification of transmission chains, and very-large data sets can be analysed through parallel computation. Here we propose and validate a new methodology for the partition of large-scale phylogenies and the inference of transmission clusters. This approach, on the basis of a depth-first search algorithm, conjugates the evaluation of node reliability, tree topology and patristic distance analysis. -

Density-ratio based clustering
Discovering clusters with varying densities
This site provides the source code of two approaches for density-ratio based clustering, used for discovering clusters with varying densities. One approach is to modify a density-based clustering algorithm to do density-ratio based clustering by using its density estimator to compute density-ratio. The other approach involves rescaling the given dataset only. An existing density-based clustering algorithm, which is applied to the rescaled dataset, can find all clusters with varying... -

...PollenF is capable of measuring all pollen features such as Polar axis, Equatorial diameter, Colpus length, Colpus width, Porus length, Porus width, Spine length, Spine width, Exine and Intine thickness, P/E and Pollen shape. The software supports .jpg, .jpeg, .png, .bmp, .gif, .tif and .tiff formats. To calibrate the software, a known distance on the image (e.g. a scale bar) is required. Users identify a line in the image of which the length is known before the tracing, and then use the scale option to set a scale. All calculations are then automatically reported in micrometers.

Zika-RNAseq-Pipeline
An open RNA-Seq data analysis pipeline tutorial
RNA-seq analysis is becoming a standard method for global gene expression profiling. However, open and standard pipelines to perform RNA-seq analysis by non-experts remain challenging due to the large size of the raw data files and the hardware requirements for running the alignment step. Here we introduce a reproducible open source RNA-seq pipeline delivered as an IPython notebook and a Docker image. -

MORO can conveniently analyze the relationship between network modularity and robustness. We employed an existing algorithm to analyze the modularity of directed graphs and a Boolean network model for robustness calculation. In particular, to ensure the robustness algorithm’s applicability to large-scale networks, we implemented it as a parallel algorithm by using the OpenCL library. A batch-mode simulation function was also developed to verify whether an observed relationship between...

CRFasRNN
Semantic image segmentation method described in the ICCV 2015 paper
CRF-RNN is a deep neural architecture that integrates fully connected Conditional Random Fields (CRFs) with Convolutional Neural Networks (CNNs) by reformulating mean-field CRF inference as a Recurrent Neural Network. This fusion enables end-to-end training via backpropagation for semantic image segmentation tasks, eliminating the need for separate, offline post-processing steps. Our work allows computers to recognize objects in images, what is distinctive about our work is that we also recover the 2D outline of objects. Currently we have trained this model to recognize 20 classes. This software allows you to test our algorithm on your own images – have a try and see if you can fool it, if you get some good examples you can send them to us. ... -

ooPorter
A Porter stemming or stemmer algorithm coded in ooRexx
This is an ooRexx line-by-line port from Ansi-C to ooRexx of the stemming routine published by Martin Porter 1980. The original source code from Porter has been commented out and emulated by the corresponding (oo)Rexx code as far as possible. This is not an example of good or fast (oo)Rexx programming, it is merely a demonstration of the Porter stemming routine ported to ooRexx, use and modify as necessary. Input to the program is a textfile with words to be stemmed, one per line.... -
