Abstract :
Using the structure deviation degree, a new function based on gradient error is put forward to evaluate the image quality of EIT. The method using the Sobel operator and gradient error information can effectively reflect the reconstruction quality of EIT image. The simulation study results suggest that the method of this paper has a better evaluation performance for reconstruction quality of EIT image.
