2) Quality control functions such as image rotation, image deskew, despeckle
, and background suppression.
Cheng, "Comparison of despeckle
filters for breast ultrasound images," Circuits, Systems, and Signal Processing, pp.
Thus, we propose to despeckle
an SAR image by minimizing the L0-norm of the difference of average of the image.
9653 respectively, after the despeckle
, gaussian (3%) attacks.
The methods are - Spatial for high frequency or fine noise, Threshold for light grain, Temporal for heavy or large grain and noise patterns, and Despeckle
for uneven grain and/or noise.
Noise reduction (type, such as despeckle
, Gaussian blur)
Available effects include Adding Text, Anti-Alias, Average, Contrast, Deskew, Despeckle
, Emboss, Gamma Correct, Grayscale, Hue, Intensity, Invert, Median, Mosaic, Motion Blur, Oilify, Posterize, Saturation, Sepia Tone, Sharpen, Solarize, Stamp, and more.
I used the program's despeckle
filter to soften the apparent graininess.
Images can be processed (Add Noise, Anti-alias, Average, Brightness, Color Resolution, Contrast, Despeckle
, Emboss, Gamma Correct, Gaussian Filter, Grayscale, Hue, Intensity Detect, Invert, Median, Mosaic, Motion Blur, Oilify, Posterize, Remove Redeye, Saturation, Sharpen, Shear, Solarize), and the functions can be applied directly from the context menu, offering a very streamlined experience.
