Obviously a Major Malfunction...: Fun with Masked ROMs - Atmel MARC4 At Aperture Labs we have Code Monkeys and Chip Monkeys. Chip Monkeys do the dangerous stuff, while we Code Monkeys sit in our nice safe offices playing with bits and bytes and other things that can't hurt us... Now, you're probably wondering what could possible be 'dangerous' in an IT Security business, and that's a perfectly fair question. How about boiling nitric acid for a start? OpenCV 3 Image Thresholding and Segmentation Thresholding Thresholding is the simplest method of image segmentation. It is a non-linear operation that converts a gray-scale image into a binary image where the two levels are assigned to pixels that are below or above the specified threshold value.

XSL Transformations (XSLT) Abstract This specification defines the syntax and semantics of XSLT, which is a language for transforming XML documents into other XML documents. XSLT is designed for use as part of XSL, which is a stylesheet language for XML. In addition to XSLT, XSL includes an XML vocabulary for specifying formatting. XSL specifies the styling of an XML document by using XSLT to describe how the document is transformed into another XML document that uses the formatting vocabulary. Digital Camera Interface Iñaki Navarro Oiza Report ::: Code ::: Slides Introduction The aim of this project is the development and construction of an interface between a CMOS camera and a computer. This interface allows a user to get images from the camera, to change some of the properties of the camera as brightness, luminance, etc from a computer. Also some image process is implemented allowing the camera to track white objects and follow them with a servomotor.

Training Haar Cascades For better or worse, most cell phones and digital cameras today can detect human faces, and, as seen in our previous post, it doesn’t take too much effort to get simple face detection code running on an Android phone (or any other platform), using OpenCV. This is all thanks to the Viola-Jones algorithm for face detection, using Haar-based cascade classifiers. There is lots of information about this online, but a very nice explanation can be found on the OpenCV website. (image by Greg Borenstein, shared under a CC BY-NC-SA 2.0 license) It’s basically a machine learning algorithm that uses a bunch of images of faces and non-faces to train a classifier that can later be used to detect faces in realtime. The algorithm implemented in OpenCV can also be used to detect other things, as long as you have the right classifiers.

The Forms Working Group The Forms working group is chartered by the W3C to develop the next generation of forms technology for the world wide web. The mission is to address the patterns of intricacy, dynamism, multi-modality, and device independence that have become prevalent in Web Forms Applications around the world. The technical reports of this working group have the root name XForms due to the use of XML to express the vocabulary of the forms technology developed by the working group. C328R Jpeg camera and .NET Micro Framework One of the cool devices I wanted to get work with .NET Micro Framework was a camera. Problem with most of the camera is, that it's using almost 20 pins when connecting to CPU. There are eight pins for Y-bus (gray-scale image) next eight for U-bus (color channel) and three pins for clock, frame-sync and h-sync. After that, camera is usually required to be connected over I2C, for configuration settings (brightness, contrast, rotation etc.) Luckily there is the company called COMedia Ltd., producing still image cameras connected over serial interface.

Coding Robin Open this page, allow it to access your webcam and see your face getting recognized by your browser using JavaScript and OpenCV, an "open source computer vision library". That's pretty cool! But recognizing faces in images is not something terribly new and exciting. Wouldn't it be great if we could tell OpenCV to recognize something of our choice, something that is not a face? Let's say... a banana? Book excerpt: Converting XML to spreadsheet, and vice versa Often it is useful for XML data to be presented as a spreadsheet. A typical spreadsheet (for example, a Microsoft Excel spreadsheet) consists of cells represented in a grid of rows and columns, containing textual data, numeric data, or formulas. An Excel spreadsheet defines some standard functions such as SUM and AVERAGE that you can specify in cells. The Apache Jakarta POI project provides the HSSF API to create an Excel spreadsheet from an XML document or to go the opposite way, parsing an Excel spreadsheet and converting to XML.

Video Production Module for Altera DE2 Board The green screen is very stable. There is no noticeable flickering in it. When testing the green detection using a green image on a VGA monitor, there was a one or two pixel green border around the edge of objects in front of the green screen. Image Segmentation pff's homepage Below is a C++ implementation of the image segmentation algorithm described in the paper: Efficient Graph-Based Image Segmentation Pedro F. Felzenszwalb and Daniel P.

String String is a class built into the Java language defined in the java.lang package. It represents character strings. Strings are ubiquitous in Java. Study the String class and its methods carefully. It will serve you well to know how to manipulate them skillfully.
