LEADTOOLS functions in the Image Arithmetic category

Apply logical and linear or nonlinear mathematical operations to the image. The user can apply these functions using one image and a factor, or two images together, or a list of images. The arithmetic functions can be used to control brightness, remove noise, improve night vision, or to create an artistic effect.

Functions Available in Image Arithmetic

Alpha Blend
Combines image data from two images, using the specified opacity value.
Multiply
Increases or decreases the brightness in the image by multiplying its colors with constant.
Add Weighted Bitmaps
Adds or averages the images in a list according to their weight factors, this function minimizes the noise and improves night vision images
Math Function
Re-mapping the image colors according to a mathematical function such as square, log, square root, sine and cosine.
Apply Mathematics or Logic Operation
Perform specific mathematical or logical operations on the colors of an image
Combine
Combines image data from two images (source and destination), letting you specify the areas to be combined, the operations to be performed when combining the data, and which color planes (R or G or B or R, G, and B) are used.
Add Bitmaps
Adds or averages the images in a list.
