Single Value Threshold from Image Histogram – Image Segmentation

Single value thresholding is a very important part of image segmentation. There are several use of image thresholding. One of the most common use is to generate a black and white image from any image. What is Image Thresholding? Thresholding or Image Thresholding is a process to dividing the total element or image into multiple segment depending on some values in the range. For example, if you…

How to Modify Intensity Level Resolution of Grayscale Image in MATLAB?

Intensity Level Resolution means number of pixels per square inches. The more the intensity resolution the more it provide a clear view. As well as the less the frame size is the more the image is clear. So, intensity level resolution is somehow related to the view frame. A image in mobile may seems clear than pc. Zooming in the image reduce intensity level resolution and zooming out increase…

How to Modify Spatial Resolution of a Grayscale Image in MATLAB?

Spatial Resolution is the total number of pixels in the picture. If the spatial resolution is good the image is more clear. An image can be showed clear when it is zoom outed. Because when you zoom out an image that means there is more pixels in a specific range than before. So, the spatial resolution is greater in that case. Modifying spatial resolution means either decreasing spatial…
