JMicroVision is an image analysis toolbox for measuring and quantifying components of high-definition images. The program contains most of the common image processing operations, has a simple and intuitive user interface, an efficient visualization system and innovative features. It contains tools to quantify either manually or automatically.Features: • Read images in TIFF, BMP, FlashPiX, GIF, JPEG, PNG, and PNM formats • Efficient visualization system • Quantify components: objects or background • Object analysis (size, shape, orientation, texture ...) • Object classification • Image processing (binary and morphology operations, filtering, segmentation...) • Image rectification (geometric corrections by control points) • Digital point counting • Tools for data collection in one or two dimensions • Image annotation and description card • Profile (variation of granulometry, density, objects or background) • Save all measures, data, calibration and preferences in a single project file
