Abstract
A method for evaluating image quality is provided. The method may include: obtaining an image, the image including a plurality of elements, each element of the plurality of elements being a pixel or voxel, each element having a gray level; determining, based on a maximum gray level of the plurality of elements, one or more thresholds for segmenting the image; determining one or more sub-images of a region of interest by segmenting, based on the one or more thresholds, the image; and determining, based on the one or more sub-images of the region of interest, a quality index for the image.
Claims20
A method implemented on at least one machine each of which has at least one processor and at least one storage device for evaluating image quality, the method comprising:
- obtaining an image;
- determining one or more sub-images of a region of interest by segmenting the image;
- and
- determining, based on the one or more sub-images of the region of interest, a quality index for the image, wherein the quality index is associated with a regularity degree of the image and a sharpness degree of the image.
A system for evaluating image quality, comprising:
- at least one storage device storing a set of instructions;
- and
- at least one processor in communication with the storage device, wherein when executing the set of instructions, the at least one processor is configured to cause the system to perform operations including:
- obtaining an image;
- determining one or more sub-images of a region of interest by segmenting the image;
- and
- determining, based on the one or more sub-images of the region of interest, a quality index for the image, wherein the quality index is associated with a regularity degree of the image and a sharpness degree of the image.
A non-transitory computer readable medium storing instructions, the instructions, when executed by at least one processor, causing the at least one processor to implement a method comprising:
- obtaining an image;
- determining one or more sub-images of a region of interest by segmenting the image;
- and
- determining, based on the one or more sub-images of the region of interest, a quality index for the image, wherein the quality index is associated with a regularity degree of the image and a sharpness degree of the image.
