This type of image is called a representative colour image. Normally one would assign colours to these exposures in chromatic order with blue assigned to the shortest wavelength, and red to the longest.

Destination image Issues: How do we specify where every pixel goes? (mapping) Source image

It is the cornerstone upon which signal and image processing is built. This short chapter can not be a comprehensive survey of linear algebra; it is meant only as a brief introduction and re-view.

One of the most common methods for filtering an image is called discrete convolution. (We will just call this “convolution” from here on.) “Flipping” the kernel (i.e., working with h[-i]) is mathematically …

Upsampling an image • How do we increase the size of an image by a factor of two? Let’s increase the resolution of the sampling grid!

If your image is a color image (RGB), but there is no important color information in the image (e.g. fluorescence; non-stained DIC), then it’s best to convert the file to monochrome (black and white): go …

Types of image data are divided into two primary categories: bitmap and vector. Bitmap images (also called raster images) can be represented as 2-dimensional functions f(x,y), where they have pixel …
