Methods of noise reduction and edge enhancement in image processing. An exemplary method comprises extracting a plurality of pixels from the video signal, evaluating measures of edge existence in a plurality of directions within the extracted pixels, determining a level of variation from the measures ...
Image processing entails numerous topics. One is edge enhancement, which is the process of applying mathematical techniques to clarify the boundaries between regions in an image. In a sense, edge enhancement is an attempt to convert a photograph into a line drawing. Another activity in image analy...

On the other hand, if we are interested in enhancing edges that are consistent with the kernel and suppressing those that are not, the output image may be added to the original input image. This addition will most likely result in a nonnegative image. Figure 6 illustrates enhancement after ...
Image processing methods and systems for noise reduction and edge enhancement. A variation detector is provided to evaluate measures of edge existence in a plurality of predetermined directions within pixels of a video signal, and determine a control signal according to a level of variation on the ...
Edge enhancement in the context of computer science refers to the process of selectively identifying and enhancing edges in an image, which is crucial for the human visual system to comprehend the contents of the image. This technique involves applying specific kernels to the image to highlight ho...
processing block which enhances edges, normally to make an image appear sharper to a human observer.However, excessive edge enhancement can introduce artifacts such as halos around high contrast edges, and can also accentuate noise. Excessive edge enhancement can negatively impact gradient based algorith...
