![]() Keywords: Crystal-glass two phases ImageJ Image analysis Quantitative calculation Introduction We hope the method and the ImageJ are helpful for researchers to make qualitative or quantitative judgments conveniently and there will be more extensive application space to be expected. We verify the reliability of this method, by two groups’ proportion-known samples, the mixture of potassium feldspar and glass powder glued by epikote and crystalbond509 respectively, and draw the following conclusions:(1) This method of the quantitative calculation of the crystal-glass two phases is reliable (2) We recommend using machine recognition with a gray value around 70-80 for quantitative calculation (3) If we want to verify this method, the selection of materials and adhesives as well as the observation conditions need to be carefully prepared. We tried to apply the ImageJ to image analysis of the rock sample, starting from the separation and quantitative calculation of the crystal-glass two phases. ImageJ, a free application and designed with an open architecture, can solve almost any image processing or analysis problem, widely used in biological science, material science, medicine, and aviation. The specific image analysis method relies on their supporting accessories and software some of them are limited or expensive. We often have geometric measurement, quantitative calculation and other requirements for the electronic images, formed by digital polarizing microscope or scanning electron microscope and so on.
