Geophysical inversion algorithms often introduce artifacts near sharp intensity transitions and image boundary. We presented a iterative restoration algorithms to restore the true inversion image and remove the artifacts. We also presented a ringing metric to evaluate the quality of images restored based on the human visual system. According to types of ringing artifacts, two ringing metrics is used...
The boundary ringing artifacts always appears near image boundary after deconvolution. We presented a new deconvolution image boundary ringing metric to evaluate the quality of images. First, we remove the deconvolution image boundary ringing artifact using the PDE-based method, and then we compare it with the degraded image to evaluate the boundary ringing artifact. The experimental results validate...
The edge ringing artifacts often appear nearby the image edge for the deconvolution bias. PDE-based non-linear techniques are an effective way to process the image. So a new diffusion filtering is proposed to remove the edge ringing artifact in the deconvolution image based on PDE filter. The experimental results validate the proposed edge ringing artifact filtering algorithms perform well.
The edge ringing artifacts often appears near image edge after deconvolution. We presented an iterative enhancement algorithm to remove the edge ringing artifact. We also presented an edge ringing metric to evaluate the quality of images enhanced based on the human visual system. The metric is used to assessment the edge ringing artifact based on the analysis of the structure of it. The experimental...
The edge ringing artifacts often appear nearby the image edge for the deconvolution bias. A new post filtering is proposed to remove the edge ringing artifact in the deconvolution image. The experimental results validate the proposed edge ringing artifact filtering algorithms perform well.
The edge ringing artifacts always appear near the image edge after deconvolution and degrade the image quality. In this paper, we presented a new deconvolution image edge ringing metric to evaluate the quality of image. The proposed approach is able to remove the deconvolution image edge ringing artifact by using a PDE (Partial Differential Equation)-based method and it will be compared with the degraded...
In this paper, we presented a ringing metric to evaluate the quality of images restored using iterative image restoration algorithms. A ringing metrics is used to assessment the restored images based on the Gabor filter. The experimental results validate the proposed method perform well over a wide range of restoration image ringing levels assessment. And the proposed model has given good agreement...
