More Information
Summary:The invention discloses a noise evaluation method, an image processing method, a noise evaluation device, an image processing device and a storage medium, and the noise evaluation method comprises the steps: obtaining a to-be-evaluated image which comprises to-be-evaluated pixel bits; obtaining a difference value of the to-be-evaluated pixel bit along a preset noise evaluation direction; obtaining a noise evaluation value of the to-be-evaluated pixel bit according to the difference value of the to-be-evaluated pixel bit along different noise evaluation directions; and obtaining a noise evaluation result of the to-be-evaluated image according to the noise evaluation values of all the to-be-evaluated pixel positions. The noise evaluation method is only related to the image to be evaluated, the accuracy of noise evaluation can be effectively improved, the noise evaluation method can be used after any step of image processing without affecting the accuracy of evaluation, and the effect of subsequently improving t
