Title: Joseph K Bryan: Innovator in Digital Image Registration
Introduction
Joseph K Bryan is a notable inventor based in West Melbourne, FL (US). He has made significant contributions to the field of digital image processing, holding 2 patents that showcase his innovative approach to image registration.
Latest Patents
One of Bryan's latest patents is a mechanism for registering digital images obtained from multiple sensors. This invention involves transforming first and second digital images, such as terrestrial images captured by spaceborne or airborne sensors, onto a registration surface according to the geometry models of the sensors. The process ensures that the digital images are aligned on the registration surface. Initially, the images are subsampled to create reduced spatial resolution versions. For each base resolution version, neighborhoods of pixels associated with matching point grids are defined. The edge-preemphasized contents of these neighborhoods are cross-correlated to measure misregistration. Bryan's method modifies the geometry models based on this measure, effectively decreasing misregistration. The cross-correlation process is repeated for higher spatial resolution versions, improving registration error correction.
Another significant patent by Bryan is a user interface mechanism for interactively manipulating displayed images. This invention translates coordinate system parameters from screen-based image manipulation software to latitude and longitude parameters of a co-registration surface-based coordinate system. Users can specify image manipulation operations for multiple images imported into respective display windows. The registration surface coordinate system parameters are compatible with image collection geometry models, allowing for seamless transformation of pixel values. The geometry models are mapped through a cascaded mapping function, coupling new pixel values to the output display for user exploitation.
