What is threshold in photography?
Definition: An image processing method that creates a bitonal (aka binary) image based on setting a threshold value on the pixel intensity of the original image. … The thresholding process is sometimes described as separating an image into foreground values (black) and background values (white).
How do I make an image threshold?
The idea is to separate the image into two parts; the background and foreground.
- Select initial threshold value, typically the mean 8-bit value of the original image.
- Divide the original image into two portions; …
- Find the average mean values of the two new images.
- Calculate the new threshold by averaging the two means.
What is a threshold value?

Why do we use thresholding in image processing?
In thresholding, we convert an image from color or grayscale into a binary image, i.e., one that is simply black and white. Most frequently, we use thresholding as a way to select areas of interest of an image, while ignoring the parts we are not concerned with.
How is threshold value calculated?
Data is collected for first statistic. When compared with the Threshold value, if the Threshold type is percentage (for the second statistic) data is collected. Both will be divided and the result will be multiplied by 100, thus giving a percentage. This resultant value will be compared with 80, i.e., Threshold value.
What is the minimum threshold?

What is a high threshold?
A ‘high’ threshold means a person or thing will only pass to that other state (eg being scared) later than the norm. A ‘low’ threshold means a person will pass to the other state earlier than the norm.
What is equalize in Photoshop?
