This is because edge detection tries to find out significant transitions in luminosity/brightness in an image. Therefore grayscale images are used, since in grayscale the brightness of an image is modeled.
You can of course use other characteristics of a pixel (like the red color) if the scene is illuminated in red or if the edges to be detected belong to objects that reflect the red color specter most.
What else can I help you with?
Why you use gray image in image processing?
gray scale so that we can process our image
What is use of filter in image processing?
Very many actions taken while processing images can be referred to as filtering. There are distortions and blurring and edge detection and color enhancements and all sorts of effects that fall under the "filtering" domain.
What do you need to know before you can write shape recognition programs for c plus plus?
Shape detection requires a slew of techniques, including edge detection, pattern matching, probability analysis, feature detection, middle mass and blob detection, image correlation and pixel classification. Recognising simple shapes like triangles, squares and circles is relatively easy. Use edge detection to find the border line and count the number of edges. If one line, it's a circle, three is a triangle and four is a square. You can then analyse the lengths and angles to determine more specific information, such as ellipse, right-angled triangle, rhomboid, parallelogram and so on. For more complex shapes, you'll need to use pattern matching, feature detection and probability analysis. The remaining techniques are primarily used for detecting 3D planes in a 2D image, separation and classification of objects and so on.
What is the use of gray scale ratio in adobe photoshop?
It is factor to scaling down the image.
What does on edge mean?
This is an idiom meaning that someone is anxious or frustrated. The image is of them balancing on the edge of a mood. You use this phrase when you are worrying or irritated about something.
How do you make smokey eyes?
use dark colors such as black or gray and apply it at the outer edge with a lighter color such as a purple
Why Lena images are prferred for test purpose in DIP?
Lena images are often used in digital image processing (DIP) as a standard test image due to their rich texture and variety of features, which allow for effective testing and demonstration of image processing algorithms. The image contains a range of tones and details, making it suitable for evaluating different techniques such as compression, filtering, and edge detection. Additionally, its widespread use has established a common reference point for researchers and practitioners in the field. However, it's worth noting that the use of Lena has faced criticism regarding its origins and the considerations of ethical representation in imagery.
Remove Backgrounds with Free Background Remover Tools?
Removing image backgrounds is easy these days with free online tools that use smart edge detection to separate the subject from the background. Tools like Quick Image Tools make the process fast and accurate — you can upload an image, remove the background automatically, and download a clean, transparent version within seconds. It’s perfect for product photos, profile images, or design work.

What are the usage tracing paper?
tracing paper is a thin paper (usually light gray) that you lay over an image - the image underneath can be seen well enough to be traced over with a pen or pencil. artists use tracing paper to copy an image or just to verify overall proportions before they commit it to permanent paper
