Basics of Image Convolution

Convolution is a process used for applying general-purpose filter effects like blurring, sharpening, embossing, edge detection, and more. To understand convolutions we must first understand what a convolution matrix is, also referred to as kernel. Take for example the blurring filter. In blur filter, we set each pixel to the mean of its neighbouring pixels. …

Segmenting lines in handwritten documents using A* Path planning algorithm

In this article, I will explain a widely used method for segmenting handwritten documents into individual lines. Below is a sample output from my algorithm. The below flowchart outlines the different steps involved in the segmentation process. The explained method will only work with non-skewed documents. To de-skew the document, you can refer to my …
