tnimage is a scientific image analysis program that allows you to create, edit, analyze, and produce color prints of images. It is particularly useful for analyzing images of SDS and agarose gels and X-ray or MRI images.
- Features
-
- Analysis features: Distance, angle, 1- and 2-D image calibration, densitometry, area, warping, 2D-FFT, and Fourier convolution and deconvolution of 2 images. View FFT Real or imaginary components, user-definable pixel math functions.
- Densitometry uses fuzzy k-means algorithm to automatically calculate background value for highly accurate densitometric measurements.
- Image editing features: Add labels, circles, Bezier curves, etc.; change brightness/contrast, change image depth; graphically create or modify palette in 8-bit modes. Filters: sharpen, edge enhance, Laplace, Sobel, etc. Rotate, resize, remap colors and many others.
- Transparency, color keying, and gradient fill. Rotated text in various fonts.
- Antialiased text, lines, etc. Users can easily create new menus for adding special characters such as Greek letters.
- Image registration and 2D gel spot matching
- Morphological analysis including erosion, dilation, quick segmentation, contour plots.
- Interactive warping/distortion correction in 2 dimensions
- Watershed transformation
- Rotating 3d wireframe or surface graph display of images.
- Grain counting using neural-network-like algorithm.
- TeX-like syntax for superscripts or multiple fonts in labels.
- Manual (scissors) and smart automatic selection of non-rectangular areas.
- Image formats supported: TIF, GIF, Targa, Windows BMP, JPEG, raw bytes, ASCII, and several others, as well as up to 100 user-definable custom formats. A sample configuration file for reading medical X-ray images from a Lumisys scanner is included. Plugin is provided for HDF format.
- Image depths: Image files of 1-32 bits/pixel can be imported/exported and displayed on 8,15,16,24, or 32-bit/pixel displays. Grayscale medical images greater than 8 bits can also be displayed.
- 512 images simultaneously viewable. Easily cut & paste among images. Facility for creating animated GIF images.
- Includes spreadsheet for editing images as ASCII, Hex, or RGB values for precise editing of pixel values.
- Other features: Macro language, image algebra, add/subtract/XOR images. User-friendly graphical user interface.
- Tutorials are included for deconvolution, densitometry, macro programming, and digital filtering with FFT.
- Scanner and digital camera interface (Unix version only).
