Catalogue of traditional image processing methods

Want to make your photos instantly black and white, with incredible contrast? Then try threshold processing! This paper will introduce the principle and setting method of threshold processing in detail to make your picture look brand-new.

What is the threshold?

Threshold processing is an image processing method. By setting the threshold of brightness value, the pixels below the threshold in the image become black, and the pixels above the threshold become white, thus improving the contrast and visual effect of the image.

How to set the threshold?

The choice of threshold is very important! Generally speaking, it is recommended to use a value of 3 to 4. Exceeding 10 may make the image look too stiff and ugly. The setting of the threshold can be adjusted according to the actual needs to achieve the best effect.

Other functions of the threshold

In addition to making the image black and white, the threshold can also be used to set the minimum value of some performance characteristics to ensure that they are not lower than a certain standard. For example, in image recognition, we can screen the image features that meet the requirements by setting thresholds.

abstract

Threshold processing is a powerful tool in image processing, which can instantly improve the contrast and visual effect of images. Threshold setting needs to be adjusted according to actual needs to achieve the best effect. Come and try it, and instantly make your picture look brand-new!
