In python the while loop needs to be controlled by making some provision inside the body of the loop to drive the condition mentioned in the beginning to false. This is usually done by keeping count of iterations. If the while loop condition never evaluates to False, then we will ... Read More

In python there are two number data types: integers and floats. In general integers do not have any decimal points and base value is 10 (i.e., Decimal). Whereas floats have decimal points. Python provides some built−in methods to convert floats to integers. In this article we will discuss some of ... Read More

To convert an integer to a character in Python, we can use the chr() method. The chr() is a Python built−in method that returns a character from an integer. The method takes an integer value and returns a unicode character corresponding to that integer. Syntax char(number) Parameter The method ... Read More

A histogram is a graphical representation showing how the pixel intensities (ranging from 0 to 255) are distributed in an image. For a digital image histogram plots a graph between pixel intensity versus the number of pixels. The x-axis has intensity variations, and the y-axis indicates the number of pixels ... Read More

An image with reversed brightness is referred a negative image, in which the light parts of the image appear dark and the darker parts appear lighter. The negative transformation of a colored image (RGB image) will be reversed, with red areas appearing cyan, greens appearing magenta, and blues appearing yellow. ... Read More

OpenCV is an Open Source Computer Vision Library in python. It provides numerous functions to perform various Image and video processing operations.
