An image desired to be reproduced is scanned to determine its video pixel gray values. A histogram generator generates a histogram distribution representing a frequency of the gray values. The histogram distribution is analyzed to determine a background peak gray value of the image and a standard deviation of the histogram distribution based on a Gaussian approximation. A thresholding circuit dynamically adjusts the background peak value based on the standard deviation and a selected scaling factor to generate a background threshold value. The background threshold value expands a range of background gray values in the image which are eliminated during image reproduction. Eliminating substantially all background gray values improves the quality of the reproduced image.

In an image reproduction system, an image processor analyzes a hierarchy of image representations of different resolutions to detect edges. In regions having edges that are detected in all hierarchical representations, little or no filtering is applied to the image. In regions having no edges or edges that are detected in only the highest-resolution representation, greater amounts of filtering are applied to the image. In regions having edges detected in two or more but not all hierarchical representations, an intermediate amount of filtering is applied to the image. In preferred embodiments, two-dimensional averaging filters of varying size are applied to the image. The size of the averaging filter is selected according to the number of hierarchical representations in which an edge is detected.

A server is restored by creating an image of a local drive of a server; replacing a driver in the boot up procedure of the server, the replacement driver redirecting disk drive access requests from the local drive to the image; on-demand copying portions of the operating system needed for start up from the image to memory of the server; and copying a remainder of the image from the image to the local drive as a background process. The data is copied on-demand from the image to the local drive. The copying is performed over a network. The image is created on a different server connected to a network. The copying of the remainder of the image, after critical start-up data has been copied, is done based on a priority of a sector of the image being copied. A bitmap is created corresponding to sectors of the image, and the server decides whether to access a particular sector on the local drive or on the image based on the bitmap.
