... was trying to do 3D on early computers - big BW pixels! By late 80s I saw ray tracing and had to write my own. I wrote the 1st ver while taking vector calculus and CAD programming classes c. '92. I was intrigued not only by the beauty of the math but also ray tracing curved metals. This is actually the 2nd ver, ported from MFC to gnome (with enhancements like optional GL) c. '00 with some help from David. Apr'17: Updated to compile on recent Ubuntu/Debian - still runs, even on a pi!

ImgView is a sim­ple im­age view­er for Linux/Unix. It is free from menus and oth­er GUI gad­gets, and con­trolled pri­mar­i­ly by the key­board. It supports the following image file formats: GIF, JPEG, PCX, PNG, PNM (PBM/​PGM/​PPM), TIFF and XBM. It is able to scale images with non-square pixels so that they display correctly on a display with square pixels. It sup­ports RGB, Gray and CMYK ICC pro­files in TIFF and JPEG, RGB and Gray ICC pro­files in PNG, and RGB ICC pro­files in GIF. Dis­play...

A font rendering engine for embedded systems. Draw high quality anti-aliased fonts on low to medium power embedded systems. The engine is a single small standard C file which needs to be included in your project. The Font tool creates a standard C file version of any font installed on your OS (Windows, Linux, Mac). All you need to implement is the draw pixel function for your hardware. Requires very little RAM as the only buffering is a line of pixels up to the width of your text.

A real-time graphics effect able to increase the resolution of small bitmaps guessing the missing pixels without blurring the images.

The Fish4knowledge project investigated: information abstraction and storage methods for analyzing undersea video data (from 10E+15 pixels to 10E+12 units of information), machine and human vocabularies for detecting & describing fish, flexible process architectures to process the data and scientific queries and effective specialised user query interfaces. A combination of computer vision, database storage, workflow and human computer interaction methods were used to achieve this. The project...

A paint program where the canvas is the visual cortex of a simple kind of artificial intelligence. You paint with the mouse into its dreams and it responds by changing what you painted gradually. There will also be an API for using it with other programs as a general high-dimensional space. Each pixel's brightness is its own dimension. Bayesian nodes have exactly 3 childs because that is all thats needed to do NAND in a fuzzy way as Bayes' Rule which is NAND at certain extremes. NAND can be...

PhotoResizerQt is a simple program to re-size one or several photos. The photos can be previewed and a suffix is added to the photo name to indicate the size. For example, x800 is added to a filename when a file is re-sized to 800 pixels. Check Forum

PerceptualDiff is an image comparison utility that compares two images using a perceptual metric. That is, it uses a computational model of the human visual system to determine if two images are visually different, so minor changes in pixels are ignored.

Thumbnail steganography creates a thumbnail from a source image and stores data in it by altering it's color channels. To decipher the data, a new thumbnail is made from the original image and the differences between the pixels are calculated.

Pixel Toaster is a portable open source framebuffer library for C++. It provides a fast and easy way to get your pixels on the screen. Floating point and truecolor pixel formats are supported on Windows, Mac and Unix.
