The present invention provides a method, system and image to enhance the image contrast of a digital image device while simultaneously compensating for image intensity inhomogeneity, regardless of the source. The present invention corrects intensity inhomogeneities producing a more uniform image appearance. Also, the image is enhanced through increased contrast, e.g., tissue contrast in a medical image. The method makes no assumptions as to the source of the inhomogeneities, e.g., physical device characteristics or positioning of the object being imaged. In the method, the error between the histogram of the spatially-weighted original image and a specified histogram is minimized. The specified histogram may be selected to increase contrast generally or particularly for accentuation, e.g., on localized regions of interest. The weighting is preferably achieved by two-dimensional interpolation of a sparse grid of control points overlaying the image. A sparse grid is used rather than a dense one to compensate for slowly-varying image non-uniformity. Also, sparseness reduces the computational complexity, as the final weight set involves the solution of simultaneous linear equations whose number is the size of the chosen grid.

Methods, systems, and media are shown for calculating an estimated amount of time needed to read a document. The estimate is based on historical session data. Reading sessions are identified in part by excluding sessions that include non-reading user behavior signals, such as adding text to the document, printing, or changing formatting. Reading sessions are further identified by generating session clusters based on shared attributes, and for each cluster, determining if a relationship exists between session time and the shared attribute. If a relationship exists, sessions are excluded if they don't fit the relationship. Once reading sessions are identified, coefficients for a formula are generated that are applied to an unseen document to estimate reading time. Each coefficient is associated with an element type. The coefficients are derived by iteratively analyzing documents with one unknown element type and subtracting out contributions of known element types.
