Which edge detection method is best?
The Canny Edge Detection algorithm is a widely used edge detection algorithm in today's image processing applications.
What is low contrast image?
A low contrast image blends light and dark areas, creating a more flat or soft photo. There are hardly any highlights and shadows and the images are composed mostly in shades of gray. This dullness in the composition of lights and darks will mute the colors in the image.
Which filter is used for edge detection in images?
The Laplacian filter, which can be used to emphasize the edges in an image, highlights the regions in which there is a rapid intensity change using a discrete convolution kernel that approximates the second derivatives of the image in the definition of the Laplacian.
