Free image processing software software for windows

Process you images in no time with the easy to use, open source, free and stable Image processing lab! IPlab is a free and easy-to-use image processing sowftware. The best thing about it all is, its open source! Coded in C#, you can download the source code, and edit it to your liking. If you are going to redistribute, please make sure it abides to the copyright. Some useful features are not included in the current version of iplab, but there is another open source application that has accessories that you may want to integrate with IPlab.
Main features:
- Color filters (grayscale, sepia, invert, rotate, channel extraction, channel replacing , channel filtering, color filtering, Euclidean color filtering);
- HSL filters (linear correction, brightness, contrast, saturation, hue modifier, HSL filtering);
- YCbCr filters (linear correction, YCbCr filtering, channel extraction/replacement);
- Binarization filters (threshold, threshold with carry, ordered dithering, Bayer dithering, Floyd-Steinberg, Burkes, Jarvis-Judice-Ninke, Sierra, Stevenson-Arce, Stucki dithering methods);
- Automatic binarization (simple image statistics);
- Mathematical morphology filters (erosion, dilatation, opening, closing, hit & miss, thinning, thickening);
- Convolution filters (mean, blur, sharpen, edges, Gaussian);
- 2 Source filters (merge, intersect, add, subtract, difference, move towards, morph);
- Edge detectors (homogeneity, difference, sobel, canny);
- Blob counter, connected components labeling;
- Pixellate, simple skeletonization, jitter, shrink, oil painting;
- Levels linear filter, gamma correction;
- Median filter, adaptive smoothing, conservative smoothing;
- Resize and rotate;
- Texture generators based on Perlin noise;
- Texture filters (texturer, textured filtering, textured merging);
- Fourier transformation (lowpass and hipass filters).

A small tool to visualise different graphic processes. It was written as a final year project in Visual C++. It loads in pictures and allows the user to apply different filters by choosing the coefficients as well as the matrix size.

BIMP is a small and simple batch processor for image files, that allows you to perform various functions on multiple images.
It can be used to create thumbnail images from your pictures, add a prefix/postfix, replace spaces in the file name with underscores, flip or rotate images and also apply anti-aliasing and emboss effects.
BIMP Batch Image Processor is a software that allows you create thumbnail images.
The thumbnail resizing allows you to force a specified width or height and keep the proportions, or define fixed image dimensions.
In addition, the program can also convert the file format to GIF, JPG, TIFF, PNG, BMP, MIFF or TGA. All of the actions can be performed individually, or combined.
Enhancements:
- Fixed overflow problem (I think)
- File rotate setting now resets when it should
- Error reporting now includes all settings
- German translation (Thanks Jochen)

Image Robot 1.2 offers you a powerful one-stop source for batch image processing. You can easily convert a variety of image file formats, resize images and create and apply an optimized palette to any number of images, all in a batch process mode. No programming is necessary... simply select the image files and the batch process commands you would like to use and Jasc Image Robot does the rest in a fraction of the time it would take to edit each file separately.

RoboRealm provides you with an interactive and experimentation vision system to investigate the very complex world of image analysis and image processing. Through an easy to use analysis pipeline you can add image processing filters to translate an image into robotic movements, computer actions, or just plain fun! RoboRealm is free to download!
Image and/or video processing can be technically difficult. Home robots are continuously moving towards high powered PC based systems that are capable of supporting complex image processing functions. Sometimes you just need a testbed of current image processing applications to test potential ideas that you want your robot or computer+webcam application to perform. Weve compiled several image processing functions into a freely available windows based application that you can use with your computers webcam. You can use it to test out your vision ideas and see what may be possible or not ... have fun! We did!

Image Filter Tester is an image processing application that applies any number of layers of user-defined filters to an image and immediately shows the result.
Main features:
- You may drag-and-drop to open an image file, or paste from clipboard.
- The image views are fully interactive. The images can be zoomed, moved, flipped, or rotated.
- The images can be copied, saved or printed.
- Image Filter Tester 1.1 runs under Windows 9x, NT, 2k, XP.
- No additional DLL (such as MFC or VB) is required.
- No installation is needed.
