Download scientific diagram | Spatial pχ 2 error map for the examples shown in Fig. 2. Error map is displayed within the range [0,1]. The corresponding ultrasound image is shown below the...

Filtering in the spatial domain (Spatial Filtering) refers to image operators that change the gray value at any pixel (x,y) depending on the pixel values in a square neighborhood centered at (x,y)

Any Max-Flow/Min-Cut algorithm will find an optimal seam which goes through minimum error path (minimum cut - highlighted in red): As you can see, the seam have successfully avoided …

Geometric distortion is an error on an image, between the actual image coordinates and the ideal image coordinates which would be projected theoretically with an ideal sensor and under ideal …

Accordingly, this paper attempts to propose an alternative irregularity reduction algorithm built on a 2-stage identification and adaptive median filter (AMF) with under fix magnitude impulsive...

Unsharp masking is an image manipulation technique for increasing the apparent sharpness of photographic images. The "unsharp" of the name derives from the fact that the technique uses …

– Internal radiometric errors include sensor malfunction and improper calibration. – External radiometric errors include atmospheric effects (“fixed” with atmospheric correction).

Submillimeter laser steering accuracy was demonstrated with a mean error < 0.20 mm. MRI compatibility testing demonstrated zero observable image artifacts during robot operation.

First, we analyze vector color error diffusion based on a new matrix gain model for the quantizer, which linearizes vector error diffusion. The model predicts key characteristics of color error …
