Detailed Description

template<class T>
class ImageCacheMinMax< T >

image cache to compute a running min/max

In this implementation, all the computations are done when getMax() or getMin() are called. That is, the cache is fairly dump and does not attempt to keep an updated min and max image as new images get added or removed. This differs substantially from the ImageCacheAvg implementation, where all computations are done as images are added/removed and getting the mean is a very cheap operation.

Constructor & Destructor Documentation

template<class T >

ImageCacheMinMax< T >::ImageCacheMinMax ( ) [inline]

Uninitialized constructor.

By default, cache size is not limited. A limit can be set later using setMaxSize().

Definition at line 236 of file ImageCache.C.

template<class T >

ImageCacheMinMax< T >::ImageCacheMinMax ( uint maxSize ) [inline]

Constructor.

Parameters:

maxSize

the maximum size of the cache. If this size is exceeded, images are popped off the front of the cache and disregarded for the computation of the mean. If maxSize = 0, the cache is not limited.
