Ship Agents Faster
Transform your applications and workflows into powerful agentic systems at global scale.
Gemini Enterprise Agent Platform lets you rapidly build, scale, govern and optimize production-ready agents grounded in your organization's data. The platform enables developers to build custom or pre-built agents for virtually any use case. New customers get $300 in free credits.
Maui is a multi-purpose automatic topic indexing algorithm. Given a document, Maui automatically identifies its topics. Depending on the task topics are tags, keywords, keyphrases, vocabulary terms, descriptors or Wikipedia titles.
AlViz is a research prototype for visual ontology alignment implemented as multiple-view plug-in for Protege using J-Trees and Graphs. Based on similarity measures of an ontology matching algorithm AlViz helps to assess and optimize the alignment results
G.A.V. (Graph Algorithm Visualizer) is a tool that visualizes algorithms from graph theory. A step-by-step visualization from each different algorithm allows the user to understand the particular algorithm very easily.
Face tracking system that allows the user to interact with the computer moving the head. It's possible to move a camera in a 3D scene and the mouse in the screen. Contains also an open source implementation of the condensation algorithm.
Deploy in 115+ regions with the modern database for every enterprise.
MongoDB Atlas gives you the freedom to build and run modern applications anywhere—across AWS, Azure, and Google Cloud. With global availability in over 115 regions, Atlas lets you deploy close to your users, meet compliance needs, and scale with confidence across any geography.
Active Shape/Appearance Model Library (ASMLibrary/AAMLibrary) source code, which includes ASMBuilding/AAMBuilding as well as ASMFitting/AAMFitting algorithm. It is developped under OpenCV 1.0 for locating features in a face and face recognition.
MelodyBall generates a simulated array of soundmaking bars, on which a ball bounces and plays a melody (see www.melodyball.com). Need to fix Java/MIDI bugs and read MIDI files as source data for the algorithm to create alternate melodies.
Fair DJ is an Mserv compatible music server designed to play music in a room with several users sharing a set of speakers. The users can rate songs, and Fair DJ selects songs using these ratings and a fairness algorithm to ensure that everybody is happy.
This project covers an algorithm for face detection in color images. It was developed as a conclusion work in graduation of Computer Science at Pontifícia Universidade Católica de Minas Gerais by Breno Santos Araújo (brenopuc@gmail.com).
pcm+ is a C++ platform-independent framework for multi-core processors to develop easily real-time audio processing and synthesis algorithm with high performance and scalability.
A hierarchical representation language for music, which can be used as a human algorithmic composition tool or as a semi-automated composition tool using a genetic algorithm with human listeners as the fitness function.
JPowerGraph is a Java library for creating directed graphs for both Swing and SWT. It supports graph movement, selection, context menus, tooltips and dynamic edge creation. JPowerGraph has a spring layout algorithm based on that used in TouchGraph.
Clean implementation (in ANSI-C) of the Wavelets Transform. It works fairy good as a sparser, which can be combined with a compression algorithm (by using programs like bzip and gzip) to achieve high compression ratios (as good as mp3's).
...Purpose is to buid an MP3 player with the lowest possible cost. Works on mono files (going stereo shouldn't be very complicated). Doesn't use Helix. The huffman decoding uses a clustering based algorithm.
PyPotrace is a Python programming language binding for Peter Selinger's Potrace raster to vector conversion algorithm. No separate Potrace library or application required!
musicomp is a program which most important element is an evolutionary algorithm which uses data mining methods as a fitness function to generate monophone melodies.
This work was a project done in course of the Summer School on Image Processing 2006 (SSIP) in Szeged,Hu. Performs a snake algorithm on 512x512. Image processing tasks are done with OpenCV and the GUI is implemented with Qt4.1.
This project provides a JAVA library and a graphical user interface which implement the "FastICA" algorithm based on the paper "Fast and Robust Fixed-Point Algorithms for Independent Component Analysis (ICA)" by Aapo Hyvärinen.
Implementation of the WSOLA algorithm for time scale modification of audio without artifact introduction (ideally). It allows one to speed/slow audio without altering its pitch.
JEQ is class library written in pure Java. It implements the infinite impulse response (IIR) algorithm for bandpass filtering of sound stream. So, it represents a backend code for stereo 10/15/25/31-band equalizer.
EyesRay render a 3D scene with the raytracing algorithm. Some specifics points are: a scene loader, the support of transparency, avaibility to generate images (ppm format)...
