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... -

Spatial Interaction in Coral Reef Communities
The program allows the simulation of spatial dynamics in a benthic coral reef community under various environmental settings. Several coral species, with either massive or branching colony growth morphologies are implemented as individual colonies, which compete for space with each other as well as with macroalgae and algal turf. For more details on the first version of the program see also: Kubicek A, Muhando C, Reuter H (2012) Simulations of Long-Term Community Dynamics in Coral Reefs - How Perturbations Shape Trajectories. ... -

hSDM
R package for hierarchical species distribution models
...Such models allows interpreting the observations (occurrence and abundance of a species) as a result of several hierarchical processes including ecological processes (habitat suitability, spatial dependence and anthropogenic disturbance) and observation processes (species detectability). Hierarchical species distribution models are essential for accurately characterizing the environmental response of species, predicting their probability of occurrence, and assessing uncertainty in the model results. -

BPL
Bayesian Program Learning model for one-shot learning
BPL (Bayesian Program Learning) is a MATLAB implementation of the Bayesian Program Learning framework for one-shot concept learning (especially on handwritten characters). The approach treats each concept (e.g. a character) as being generated by a probabilistic program (motor primitives, strokes, spatial relationships), and inference proceeds by fitting those generative programs to a single example, generalizing to new examples, and generating new exemplars. The repository contains code for parsing stroke sequences, fitting motor programs, exemplar generation, classification, re-fitting, and demonstration scripts. -

Orfeo ToolBox
OTB is an open-source C++ library for remote sensing images processing
...More information is available at www.orfeo-toolbox.org It is based on the medical image processing library ITK and offers particular functionalities for remote sensing image processing in general and for high spatial resolution images in particular. Targeted algorithms for high resolution optical images (SPOT, Quickbird, Worldview, Landsat, Ikonos), hyperspectral sensors (Hyperion) or SAR (TerraSarX, ERS, Palsar) are available. Orfeo ToolBox has three main access depending on the category of user: write processing chains in C++ using existing filters or creating new ones, use the OTB applications, which is a plugin-based framework allowing to extend high-level processing chains from various environment ( command-line, QT, QGis, Python....) or use Monteverdi, a software for everyday life image manipulation and analysis. -

TTV
Tensor total variation for low-dose CT perfusion
We have developed a robust and efficient framework to accurately estimate the perfusion parameters at low radiation dosage. Specifically, we present a tensor total-variation (TTV) technique which fuses the spatial correlation of the vascular structure and the temporal continuation of the blood signal flow. An efficient algorithm is proposed to find the solution with fast convergence and reduced computational complexity. -

A General Theory of Reactivity
A General Theory of Reactivity
...Rather than introducing one application, it attempts to organize values, promises, streams, observables, tasks, generators, and related concepts into a common model. The theory distinguishes singular from plural data and spatial values from temporal ones. It also examines dual relationships such as getters and setters, readers and writers, and promises and resolvers. Tasks are presented as cancelable, unicast relatives of promises, while streams represent plural values distributed through time. The repository discusses pressure, polling, push systems, signals, behaviors, cancellation, and resource coordination. ... -

as3delaunay
Delaunay triangulation and Voronoi diagram for Flash Builder 4 project
...The library enables users to generate Voronoi diagrams from a set of input points, allowing applications such as procedural map generation, image segmentation, and spatial partitioning. By handling complex geometric relationships automatically, it simplifies the process of building interactive or data-driven visualizations. The project emphasizes performance and mathematical accuracy while maintaining readability for developers working in ActionScript. Its codebase serves as a reliable foundation for anyone implementing geometry-based algorithms or graphical systems within AS3 projects. -

chipexo
model based analysis of ChIP-exo data
...MACExo has the following four steps: 1) sequencing data normalization and bias correction; 2) signal consolidation and noise reduction; 3) single nucleotide resolution border detection using Chebyshev Inequality; and 4) border matching using Gale-Shapley’s stable matching algorithm. When applied to yeast Reb1 and human CTCF ChIP-exo data, MACE is able to define TFBSs with higher sensitivity, specificity and spatial resolution, as evidenced by multiple criteria, such as motif enrichment, sequence conservation, nucleosome positioning, and open chromatin states. -

EAS-Framework
Old Repository of the Easy Agent Simulation (deprecated since Nov. 14)
...EAS is a Java-based simulation platform, developed as part of a research project at the Karlsruhe Institute of Technology. It comes with a broad range of pre-developed simulation scenarios, ranging from virtual agents acting in abstract environments to agents with a spatial representation in 2D or 3D. It is built upon a novel architecture using a separate "plugin layer" to communicate between the simulation engine and the simulated model. This allows to flexibly add or remove non-simulation-specific functionality such as visualization, chart drawing, trajectory painting etc. Studies show that the architecture is well-suited to guide beginners quickly to simulations of various levels of complexity. ... -
