Dilation and Erosion are two primary image operations in the area of Mathematical Morphology. Dilation is applied to binary images. The main effect of the dilation on a binary image is to continuously increase the boundaries of regions of…
Python cv2: Filtering Image using GaussianBlur() Method
Image filtering functions are often used to pre-process or adjust an image before performing more complex operations. These operations help reduce noise or unwanted variances of an image or threshold.
There are three filters available in…
Python cv2: How to Filter Image Pixels using OpenCV
To filter image pixels means you can convert the image from color to grayscale or add an extra layer to the image. To convert a color image to a grayscale image, use cv2.cvtColor() method. We can then write the image to the disk using the…
