Image binary processing mechanismīinary processed image with a threshold of 127 Examples of Particle Size Distribution and Particle Size Analysis Using KEYENCE’s Latest 4K Digital MicroscopeĬonventional laser diffraction and laser dispersion methods cannot be used to observe actual particles.* What’s more, observation with microscopes requires a high degree of proficiency, and the obtained data must be analysed with different software. Performing binary processing on an image makes it possible to perform the processing of extracting just the information of whether a pixel is black or white from the required part, thereby making particle size analysis easier and faster. The range over which to perform binary processing can also be specified. Values smaller than the threshold are converted to white. Values larger than the threshold are converted to black. The value of each pixel is compared against a set arbitrary threshold. Image binary processing refers to converting an image having gradations to black and white. What Are Particle Size Distribution and Particle Size Analysis Using Image Processing? View, Capture, and Measure with Just One Device.Imaging setting reproduction and calibration.Examples of Particle Size Distribution and Particle Size Analysis Using KEYENCE’s Latest 4K Digital Microscope.What Are Particle Size Distribution and Particle Size Analysis Using Image Processing?. ![]() This section introduces examples of using the VHX Series, KEYENCE’s latest 4K Digital Microscope, to solve the problems in particle size distribution and particle size analysis. Recent digital microscopes not only have high image quality but also are equipped with particle extraction and quantification by way of image binary processing, measurement condition reproduction, and other such functions to support a variety of requirements. ![]() In recent years, high-performance digital microscopes have been added to this list of devices due to improvements in CMOS image receiving elements, lens accuracy, lighting technology, and image processing technology. Conventionally, particle analysis was performed with laser dispersion particle analysers and microscopes.
