When we resize the image we say the resolution decreases.So what is meant by resolution decreases ,does the pixel value reduces?
Resize of image in opencv
Hi @anushkajain523 Image resolution is typically described in PPI, which refers to how many pixels are displayed per inch of an image.Higher resolutions mean that there more pixels per inch (PPI), resulting in more pixel information and creating a high-quality, crisp image.Images with lower resolutions have fewer pixels, and if those few pixels are too large (usually when an image is stretched), they can become visible like the image below.
There isn’t a direct relation between pixel value and resolution
