Binary to BCD Home Purpose: Algorithm: If any column (100's, 10's, 1's, etc.) is 5 or greater, add 3 to that column. Psuedo-Code: Algorithm In Action: BCD Conversion in Hardware: How to Build a Robot Tutorials - Society of Robots Computer Vision vs Machine Vision Computer vision and machine vision differ in how images are created and processed. Computer vision is done with everyday real world video and photography. Machine vision is done in oversimplified situations as to significantly increase reliability while decreasing cost of equipment and complexity of algorithms. As such, machine vision is used for robots in factories, while computer vision is more appropriate for robots that operate in human environments. Machine vision is more rudimentary yet more practical, while computer vision relates to AI. You can also do other neat tricks with images, such as thresholding only a particular color like red. The basic shapes are very easy, but as you get into more complex shapes (pattern recognition) you will have to use probability analysis. What the algorithm does is labels each blob by a number, counting up for every new blob it encounters. In this below video, I ran a few algorithms in tandem.
11.5 Random Brute-force Search | Department of Electrical and Computer Engineering | University of Waterloo Introduction Theory HOWTO Error Analysis Examples Questions Applications in Engineering Matlab Maple The random brute-force search is the simplest stochastic search method available. However, despite its inefficiency, it remains a functional and useful tool. Moreover, its simplicity makes it a good method to study as an initiation to stochastic optimization. Useful background for this topic includes: 3. A brute-force approach is any algorithm that tries possible solutions one after the other until it finds one that is acceptable or until a pre-set maximum number of attempts. While such a brute-force approach may seem unsophisticated, it does have the advantage of being able to search any function, even one that has a complex and irregular shape, multiple local optima, and even discontinuities. It should be instinctively clear that testing more points increases the algorithm's odds of getting closer to the optimum. Given a scalar-valued function of a vector variable, Consider the function .
Электроника для всех | Блог о электронике Sparco : SPARCO: A toolbox for testing sparse reconstruction algorithms Introduction Sparco is a suite of problems for testing and benchmarking algorithms for sparse signal reconstruction. It is also an environment for creating new test problems, and a suite of standard linear operators is provided from which new problems can be assembled. Sparco is implemented entirely in Matlab and is self contained. (A few optional test problems are based on the CurveLab toolbox, which can be installed separately.) At the core of the sparse recovery problem is the linear system Ax + r = b, where A is an m-by-n linear operator and the m-vector b is the observed signal. This technical report gives an overview of the Sparco toolbox. Quick start The main interface to the test problems is through the generateProblem script found at the top-level directory. The signal generated by generatePoblem(5) >> P = generateProblem(5); This create a problem structure P which contains all the information needed to access this problem. The function handle P.A behaves as follows: Related links

Low-Rank Matrix Recovery and Completion via Convex Optimization Robust PCA We provide MATLAB packages to solve the RPCA optimization problem by different methods. All of our code below is Copyright 2009 Perception and Decision Lab, University of Illinois at Urbana-Champaign, and Microsoft Research Asia, Beijing. We also provide links to some publicly available packages to solve the RPCA problem. Note: If the code package contains a 'PROPACK' folder, please ensure that it is added in the MATLAB path before using the code. Augmented Lagrange Multiplier (ALM) Method [exact ALM - MATLAB zip] [inexact ALM - MATLAB zip] Usage - The most basic form of the exact ALM function is [A, E] = exact_alm_rpca(D, λ), and that of the inexact ALM function is [A, E] = inexact_alm_rpca(D, λ), where D is a real matrix and λ is a positive real number. Matrix Completion We provide below links to publicly available code and references to solve the matrix completion problem faster than conventional algorithms.

Robot Programming - MATLAB Robot programming involves designing the controller that governs robot behavior. Because of the growing complexity of robotics, modeling and simulation are becoming crucial to understanding how the controller interacts with the robot’s environmental perception, mobility, and interaction. Modeling and simulation help engineers refine the system design and eliminate errors before developing hardware prototypes. An ideal robot programming process includes: Modeling perception and mobility systems Using simulation to design and validate your control algorithms Generating C code from your simulation model For details, see MATLAB® and Simulink®.

Deva Ramanan - UC Irvine - Computer Vision Research Our group works on computer vision, machine learning, and computer graphics, with a focus on statistical methods for analyzing images and video. Our research tends to explore theoretical issues (such as knowlege representation and large-scale learning) that are firmly grounded in concrete applications (such as visual search and video surveillance). Historically, it has been difficult to transfer algorithms that work in controlled lab settings to unconstrained ``in-the-wild'' footage. Here's a formal bio and a sampling of recent projects we've worked on: Object recognition (PASCAL VOC Lifetime Achievement Prize) Discriminative models in vision (2009 Marr Prize) Finding and tracking people in images/videos (book chapter) Teaching Journal Publications/Book Chapters Conference Publications Workshop Publications Technical Reports Theses
