Filtering . MDP. Safety and Safety Gear. When filtering from a fermentation vessel you should never use carbon dioxide to push the beer through the filter, this can cause a potentially serious safety issue, instead use the pump to push the beer through the filter. Sanitized rubber gloves

Filtering

Filtering. Most slides from Steve Seitz. What is an image?. We can think of an image as a function, f , from R 2 to R: f ( x, y ) gives the intensity at position ( x, y ) Realistically, we expect the image only to be defined over a rectangle, with a finite range:

Attribute Filtering

Attribute Filtering. Terms: Attribute Filter Policy. A policy containing a trigger, that indicates if the policy is active, and a set of attribute value filters. Terms: Policy Requirement Rule. A specific requirement that must be met in order for an attribute filter policy to in effect.

Spatial Filtering

Spatial Filtering. Background. Filter term in “ Digital image processing ” is referred to the subimage There are others term to call subimage such as mask, kernel, template, or window The value in a filter subimage are referred as coefficients, rather than pixels.
