Layer mask allows you to obscure layer content or its part. Layer mask is gray-scale (bitmap) image: black color hides, white reveals and shades of gray partialy hides layer content.
Vector mask is created from paths and can be re-sized without damaging pixel information's.
A kernel is defined as a small central part of something. In the case of image processing it is a tool used to edit the image by sharpening, blurring , embossing it, and so on.
With selections, it will try to smooth out jagged edges.
The mean square error is used as part of the digital image processing method to check for errors. Two MSEs are calculated and then compared to determine the accuracy of an image.
a vector with nothing in it
Edges with high contrast that have shadows after compression (like rings when you drop a pebble into a pond).
A resultant vector is one vector which can replace all the other vectors and produce the same effect.

It is a measure which has a direction as well as a value.
It stands for gradient vector flow.
They work as application-layer network protocols. They used for shared access of file,image,printer and serial ports. They provide inter process communication connection.
A negative vector is a vector that has the opposite direction of the original vector but the same magnitude. It is obtained by multiplying the original vector by -1. In other words, if the original vector points in a certain direction, the negative vector points in the exact opposite direction.
Saliency is an attempt to determine which regions of an image are the most conspicuous. It's a loosely bio-inspired concept - when processing a new scene a low-level process drives rapid eye movement (called saccades) as the brain seeks to determine what it needs the eyes to focus on first. This calculation is performed by the regions V1-V4 of the primary visual cortex.
