Gets or sets a value that defines the estimated costs (time) for searching an image.
If Downsize is set as a preprocessing step, the
image and feature bitmaps are tried to be downsized so that the estimated search costs
match this value.
The time to search for an image is proportional to the product of the areas of the
image and the feature bitmap. By settings this value and the Downsize
as a preprocessing step, you can adjust the estimated search time. Note, that a reduced
search time generally reduces the size of the downsized images and thus their quality and
the similarity of the search matches.
Image and feature will only be downsized to a minimum of 30% of their original size.
