Book Description
This report covers the results of an advisory contract with directions to assist the Laser Measurement Technology Group of the US Army Missile Command Redstone Arsenal, Alabama in an initial evaluation of the potential applicability of optical pattern recognition to target identification and terminal homing systems. The initial part of the report is a tutorial survey of optical pattern recognition which includes a selected bibliography that reflects the present state of the art. Sections 1 and 2 discuss two potential applications. Preliminary calculations indicate that it is energetically practical to use optical pattern recognition techniques for target recognition over a range of five kilometers. Less detailed calculations on another possible applications indicate that detection of either intensity distributions or intensity gradients can be used for target recognition; however, electronic techniques are probably preferable to optical processing techniques. (Author).

Book Description
Progress on real-time spatial light modulators, image pattern recognition and optical signal processing for missile guidance is documented. A full description of our test and evaluation of the Soviet PRIZ spatial light modulator is inxcluded. In image pattern recognition, a unified formulation of four different and new types of synthetic discriminant functions is advanced. These include synthetic discriminant functions for intra and inter-class pattern recognition and multi-class pattern recognition. In the area of image pattern recognition, we also advance new statistical synthetic discriminant function filter concepts and a new principal component synthetic discriminant function. These analyses utilize new performance measures and new image models. Conventional holographic pattern recognition research conducted under AFOSR support is also reviewed. Our new AFOSR optical signal processing research concerns optical matrix-vecgtor processors. Initial research in this area includes fabrication of a fiber-optic microprocessor-based iterative optical processor and its use in adaptive phased array radar processing and for the calculation of eigenvalues and eigenvectors of a matrix.

Book Description
This research concerns optical data processing for missile guidance and target recognition. It uses pattern recognition techniques with an increased use of knowledge base, inference machine and associative processor techniques. This work concerns new algorithms, real time and practical realizations of such systems, and new initial work on associative processors, symbolic rule-based processors and directed graph processors (with new attention to unique optical realizations of such systems). Keywords: Optical data processing; Pattern recognition; Feature extraction; Associative processors; Symbolic processors; Rule based processors.

Book Description
Visual pattern analysis is a fundamental tool in mining data for knowledge. Computational representations for patterns and texture allow us to summarize, store, compare, and label in order to learn about the physical world. Our ability to capture visual imagery with cameras and sensors has resulted in vast amounts of raw data, but using this information effectively in a task-specific manner requires sophisticated computational representations. We enumerate specific desirable traits for these representations: (1) intraclass invariance—to support recognition; (2) illumination and geometric invariance for robustness to imaging conditions; (3) support for prediction and synthesis to use the model to infer continuation of the pattern; (4) support for change detection to detect anomalies and perturbations; and (5) support for physics-based interpretation to infer system properties from appearance. In recent years, computer vision has undergone a metamorphosis with classic algorithms adapting to new trends in deep learning. This text provides a tour of algorithm evolution including pattern recognition, segmentation and synthesis. We consider the general relevance and prominence of visual pattern analysis and applications that rely on computational models.
