A method and system for image quality assessment is disclosed. The image quality assessment method is a no-reference method for objectively assessing the quality of medical images. This method is guided by the human vision model in order to accurately reflect human perception. A region of interest (ROI) of medical image is divided into non-overlapping blocks of equal size. Each of the blocks is categorized as a smooth block, a texture block, or an edge block. A perceptual sharpness measure, which is weighted by local contrast, is calculated for each of the edge blocks. A perceptual noise level measure, which is weighted by background luminance, is calculated for each of the smooth blocks. A sharpness quality index is determined based on the perceptual sharpness measures of all of the edge blocks, and a noise level quality index is determined based on the perceptual noise level measures of all of the smooth blocks. An overall image quality index can be determined by using task specific machine learning of samples of annotated images. The image quality assessment method can be used in applications, such as video / image compression and storage in healthcare and homeland security, and band-width limited wireless communication.

Method and system for predicting consumer behavior
A method of predicting consumer response to given content. The process begins with the step of collecting a dataset of consumer response to the content, each data item including values for a selected set of segmentation variables related to past consumer behavior. The dataset contains at least twice the number of entries required to provide statistical validity. The process continues by constructing a classification tree structure using the dataset, in which the dataset is subdivided into learning and validation datasets of substantially equal size. Also, the criterion for each successive split is the lowest entropy of segmentation variables not employed to the point of such split. Each successive split of the learning dataset is performed only if that split produces child nodes statistically different from one another, and an identical split of the validation data set produces child nodes statistically similar to child nodes produced on the learning dataset. The system estimates consumer responses by first receiving a data item related to a new consumer, including values for the segmentation variables and then computing the likely response of the new consumer to the content, employing the classification tree data structure.

Method of partitioning data records
InactiveUS7272612B2Rapid and efficientMinimize timeData processing applicationsDigital data processing detailsSelf-balancing binary search treeMulti dimensional data
A tree-structured index to multidimensional data is created using occurring patterns and clusters within the data which permit efficient search and retrieval strategies in a database of DNA profiles. A search engine utilizes hierarchical decomposition of the database by identifying clusters of similar DNA profiles and maps to parallel computer architecture, allowing scale up past previously feasible limits. Key benefits of the new method are logarithmic scale up and parallelization. These benefits are achieved by identification and utilization of occurring patterns and clusters within stored data. The patterns and clusters enable the stored data to be partitioned into subsets of roughly equal size. The method can be applied recursively, resulting in a database tree that is balanced, meaning that all paths or branches through the tree have roughly the same length. The method achieves high performance by exploiting the natural structure of the data in a manner that maintains balanced trees. Implementation of the method maps to parallel computer architectures, allowing scale up to very large databases.
