Arithmetic Operations on Images - OpenCV

I want to put the OpenCV logo above an image. If I add two images, it will change the color. If I blend them, I get a transparent effect. But I want it to be opaque. If it was a rectangular region, I could use ROI as we did in the last chapter. But the OpenCV logo is a not a rectangular shape. So you can do it with bitwise operations as shown ...

Bit Manipulation Hacks | Brilliant Math & Science Wiki

In this wiki, we shall discuss a number of one liners that help us solve simple arithmetic problems in binary numbers. They are often found to be very useful (and quick) in larger programs. Because of the way numbers are represented in computers, these one liners are not only handy for the programmer but also very fast in execution. The Bitwise operators constitute the standard operators from ...

python - What does a star (asterisk) do in f-string? - Stack Overflow

@Kasrâmvd Note that using or_expr does not mean that an or-operator has to be used there - it just means that the bitwise or operator is the first operator in the precedence-hierachy that would be allowed as an operand to *. So it's just about setting the precedence of prefix * vs. infix operators.

Contour Features - OpenCV

5. Convex Hull. Convex Hull will look similar to contour approximation, but it is not (Both may provide same results in some cases). Here, cv.convexHull() function checks a curve for convexity defects and corrects it. Generally speaking, convex curves are the curves which are always bulged out, or at-least flat.

Morphological Transformations - OpenCV

OpenCV-Python Tutorials; Image Processing in OpenCV; Morphological Transformations. Goal. In this chapter, We will learn different morphological operations like Erosion, Dilation, Opening, Closing etc. We will see different functions like : cv.erode(), cv.dilate(), cv.morphologyEx() etc. Theory. Morphological transformations are some simple operations based on the image shape. It is normally ...

Image Gradients - OpenCV

Sobel operators is a joint Gaussian smoothing plus differentiation operation, so it is more resistant to noise. You can specify the direction of derivatives to be taken, vertical or horizontal (by the arguments, yorder and xorder respectively). You can also specify the size of kernel by the argument ksize. If ksize = -1, a 3x3 Scharr filter is used which gives better results than 3x3 Sobel ...

DSA Notes: Understanding Algorithm Analysis and Basic Concepts

Bitwise Operators in C++. Bitwise operators perform operations on the binary representation of numbers. Common operators include: * AND (&): Sets a bit if both corresponding bits are 1. * OR (|): Sets a bit if at least one of the corresponding bits is 1. * XOR (^): Sets a bit if the corresponding bits are different. * Left Shift (<<): Shifts bits to the left, equivalent to multiplying by ...

What is a Symbol in Computer Language? (Unlocking Code Meaning)

Operators: Symbols that perform specific operations, such as arithmetic, logical, or bitwise operations. Delimiters: Characters that define the structure and scope of code blocks. For instance, in the expression x = y + 5;, x and y are identifiers, = and + are operators, and ; is a delimiter. Each of these symbols plays a distinct role in defining the operation being performed.
