    Abstract: An image processing system that automatically optimizes the perceptual quality of images undergoing a series of selected image-processing operations. The automatic optimization capability allows the system to bypass expensive and time-consuming trial-and-error methods associated with interactive methods. The system consists of a set of image-processing operations, an architecture, and an intelligent control. These elements take into consideration profiles of sources from which the images are generated, profiles of intended applications, and the impact that image processing operations (individually or in concert) will have on perceived image quality. The analysis uses a body of relationships linking human perception of image quality with objective metrics (such as sharpness, grain, tone, and color) of image content. The relationships used are based upon extensive psychovisual testing, using human observers and photographic images. The intelligent control embodies the test results and thereby functions as a synthetic human observer. Controlling a collection of adjustable parameters in the requested image-processing operations, it works automatically to maximize subjective quality for the resulting picture. When optimal parameter values have been determined, the system then subjects the image data, itself, to the corresponding processing operations and provides an image to the end application. This is all achieved without operator intervention other than initially selecting the set of processing operations. The functionality of the system may be implemented in a variety of physical architectures, including computer workstations, and including communicating sets of discrete components in which the computations and control are distributed among the components.

    Abstract: Device profiles conventionally describe properties of a device or element within a digital image processing system that capture, transform or render color components of an image. An improved device profile includes both chromatic characteristic information and spatial characteristic information. The device profile is generated by use of both chromatic and spatial characteristic functions within a model based image processing system to predict both color and spatial characteristics of a processed image. The device profile generally includes: first data for describing a device dependent transformation of color information content of the image; and second data for describing a device dependent transformation of spatial information content of the image. In a special case, the device profile could contain only spatial characteristic information.

    Abstract: An image processing system and method for processing an input image provides a virtual observer for automatically selecting, ordering and implementing a sequence of image processing operations which will yield maximum customer satisfaction as measured by a customer satisfaction index (CSI) which, for example, can balance the image quality and the processing time. The CSI evaluates an effect of the sequence of image processing operations on the input image in response to upstream device characteristic data received from an input device profile, downstream device characteristic data received from an output device profile, host configuration data, user selection data, trial parameter values and data corresponding to the sequence of image processing operations. In a preferred embodiment, the effect is evaluated in accordance with predetermined psychovisual attributes of the input image as attained and codified by human observers who have subjectively selected a most pleasing test image corresponding to objective metrics of the predetermined psychovisual attributes.

    Abstract: Disclosed herein are a method, apparatus and computer usable medium for linear filtering with filters of any desired shape and length using the wavelet transform as the computation engine by modifying the basis functions. Specifically, the method and apparatus modifies the basis function of the wavelet and/or inverse wavelet transform(s) by convolving it with the desired filter, thereby forming a modified wavelet and/or inverse wavelet transform(s). The linear filtering is performed in the signal processing and image processing related fields using the wavelet transform with a method that is mathematically equivalent to the filtering operation in the spatial domain. Linear filtering in the wavelet based domain eliminates the need for another program for software support or additional silicon area or real estate to accommodate more functions in hardware. The modified wavelet and/or inverse wavelet transform harnesses and leverages the wavelet and/or inverse wavelet basis function of the wavelet and/or inverse wavelet transform so as to perform the desired linear filtering of the digital or analog signals, without incurring extra cost in terms of software computations or hardware modifications.
