![]() Here it looks better to use the filled ROI. When extracting a mask from a ROI you have many options ( contour, box, filled, center, hull or normal). ![]() The ROIs can then be filtered, manipulated and finally painted to an RGBA image. Image-js has a powerful Region of Interests Manager that allows to create ROIs from different sources. Try it Filter a mask using Region Of Interests (ROIs) Morphological transformations (open, close, erode.Image-js implements a number of functions to get statistics about an image: Extract individual channels (red, green or blue).Image-js can be used to do simple image manipulations such as: It can accept an arbitrary amount of color channels (usually 1 or 3) and can Image-js can work with images that have 1 (binary), 8, 16 or 32 bits per channel. Image has only one 16-bit channel and no pixel information is lost. Unlike many other libraries, if a 16-bit greyscale PNG is decoded, the resulting Have to work on images that have more that 8 bits per channel. Image-js was developed to be used in scientific applications where we often Native support for various bit depths and image kinds The following formats can be saved by image-js: TIFF (8 or 16 bits, color or greyscale, supports LZW compression). ![]() PNG (8 or 16 bits, color or greyscale, with or without alpha, palette 1 - 8 bits). ![]() The following formats can be loaded by image-js: $ npm install image-js Features Supported image formats Processing on scientific images (Region of interest (ROI), Hull curve, minimalīoundary rectangle (MBR), particle size and orientation, cell imaging, etc.). (color leveling, grey image, mask, resize, rotation, etc.) as well as advanced Image-js is a full-featured library that can deal with simple image processing Advanced image processing and manipulation in JavaScript. ![]()
