The image processor may detect a sinusoidal light waveform in the frame. The image processor may perform a sinusoidal regression. The image processor may obtain an inverted gain map. The image processor may apply the inverted gain map to the frame. The image processor may output the frame....
including oversharpening “halos” and loss of fine, low-contrast detail. These artifacts result from nonlinear signal processing (so-called because it varies with the signal). Log frequency-Contrast chartImages may be sharpened (MTF boosted) in the presence of contrasty features...
Reduction of boundary artifacts in image restoration The abrupt boundary truncation of an image introduces artifacts in the restored image. The traditional solution is to smooth the image data using special w... F Aghdasi,RK Ward - 《Image Processing IEEE Transactions on》 被引量: 104发表: ...
By comparing diffraction-limited images and super-resolution equivalents of the same acquisition volume, this approach generates a quantitative map of super-resolution defects and can guide researchers in optimizing imaging parameters. This is a preview of subscription content, access via your institution ...
Artifacts are commonly encountered in clinical CT and may obscure or simulate pathology. There are many different types of CT artifacts, including noise, b..
in the proximity of contrasty features like edges and blurred (lowpass filtered) in their absence. This generally improvesmeasuredperformance (both sharpness from slanted-edges and noise/Signal-to-Noise Ratio (SNR) from chart patches), but it may result in a degradation of perceived image quality...
Also, under "Performance": set "Use Graphics Processor" to "Custom" instead of "Auto", and then: only "Use GPU for display", and not "Use GPU for image processing". This, in combination with the upgrade to LR 13.2 seems to...

3.A phenomenon or feature not originally present or expected and caused by an interfering external agent, action, or process, as an unwanted feature in a microscopic specimen after fixation, in a digitally reproduced image, or in a digital audio recording. ...
