Difference between salt noise and pepper noise
How does one eliminate salt and pepper noise from an image?
Median filtering is effective in eliminating salt and pepper noise, where each pixel is replaced with the median value of its neighbors. Some other techniques include adaptive filtering and morphological operations.
Are there any particular instances where salt noise is more common than pepper noise?
Salt noise and pepper noise are equally likely in general because they come from the same types of errors that occur during transmission as well as storage of data. Nevertheless, specific environments or equipment limitations may make one type become dominant for a while.
Can salt and pepper noise affect color images?
Definitely, salt and pepper can impact on colored images. This results into all color channels containing both black specks termed as noises or white specks across all color channels or it may affect only individual channels producing dots of different colors. Grayscale image’s filtering techniques can be adapted to cater for color images.
Difference between Salt Noise and Pepper Noise
Digital picture handling includes the unwanted alteration of pixel values in an image which degrades the visual quality and interferes with image analysis. Several types of noise are found in digital images with “salt-and-pepper noise” being one of them, often caused by mistakes during data transmission or when capturing pictures. This type of noise manifests as random white or black pixels on an image that look like salt and pepper sprinkled over it.
