Comparison of several types of graphical projection, including elevation and plan views. To render each such picture, a ray of sight (also called a projection line, projection ray or line of sight) towards the object is chosen, which determines on the object various points of interest (for instance, the points that are visible when looking at the object along the ray of sight); those points of ...
The border option adds a one-pixel border, which can be useful when it is important to distinguish image from background. Here is the same picture with and without a border.

Solving "Spot the difference" by overlaying the left image (top left) with an inverse image (bottom left) of the right one (top right). Differences appear as non grey parts (bottom right) A way to solve a spot the difference puzzle digitally is to create a inverse version of one of the images to compare and to overlay it 50% on the other one.
Likewise, with digital cameras, images taken at higher sensitivity settings show more image noise than those taken at lower sensitivities. [ 6 ] However, even if both techniques have inherent noise, it is widely appreciated that for color, digital photography has much less noise/grain than film at equivalent sensitivity, leading to an edge in ...

For example, in the case of surface models produces using the lidar technology, one can have several surfaces – starting from the top of the canopy to the actual solid earth. The difference between the two surface models can then be used to derive volumetric measures (height of trees etc.).

A digital image is an image composed of picture elements, also known as pixels, each with finite, discrete quantities of numeric representation for its intensity or gray level that is an output from its two-dimensional functions fed as input by its spatial coordinates denoted with x, y on the x-axis and y-axis, respectively.
