Is there any way to get intensity value of a certain wavelength for given pixel of a normal image?

1. How do you find the intensity of an image?
2. How do you calculate average pixel intensity?
3. What is intensity value of pixel?
4. What is the range of intensities for a pixel in an image?

How do you find the intensity of an image?

The intensity is the sum of the RGB values normalized to 1: 1 1= 3(R + G+ B).

How do you calculate average pixel intensity?

You can divide the integrated intensity by the number of pixels in an object to get the average intensity, or multiply the average intensity by the number of pixels in an object to get the integrated intensity.

What is intensity value of pixel?

Since pixel intensity value is the primary information stored within pixels, it is the most popular and important feature used for classification. The intensity value for each pixel is a single value for a gray-level image, or three values for a color image.

What is the range of intensities for a pixel in an image?

For most images, pixel values are integers that range from 0 (black) to 255 (white). The 256 possible gray intensity values are shown below. The range of intensity values from 0 (black) to 255 (white).
