Abstract: Apparatus and methods related to applying lighting models to images of objects are provided. An example method includes applying a geometry model to an input image to determine a surface orientation map indicative of a distribution of lighting on an object based on a surface geometry. The method further includes applying an environmental light estimation model to the input image to determine a direction of synthetic lighting to be applied to the input image. The method also includes applying, based on the surface orientation map and the direction of synthetic lighting, a light energy model to determine a quotient image indicative of an amount of light energy to be applied to each pixel of the input image. The method additionally includes enhancing, based on the quotient image, a portion of the input image. One or more neural networks can be trained to perform one or more of the aforementioned aspects.

Abstract: An imaging system for superimposing at least two images, and a related method for superimposing at least two images, which images are obtained from separate or independent image sources. A single mapping based view of a user selected geographic area onto which multiple image data sets from separate computer systems are displayed whilst simultaneously isolating separate input data channels. At least one first image data set and/or a position code (generated by a position code generator) is transferred to a position code extractor via at least one secure transmission channel. The secure channel ensures isolation of input data from the separate input data channels of different computer systems. The first image is combined with a second image to provide a combined single image view of the selected geographic area. Transmission of an image data set, with associated position code, negates the need to pass data sets between separate computer systems.

Abstract: A radio transmitter is adapted to automatically adjust aerial impedance for a selected radio frequency. The radio transmitter includes a tunable radio frequency signal generator that has an impedance and is adapted to generate a radio frequency signal in the range of approximately 510 kilohertz to approximately 1705 kilohertz. The radio transmitter is also adapted to receive less than or equal to approximately 100 milliwatts of total input power. An aerial coupled to the tunable radio frequency signal generator and is adapted to transmit the radio frequency signal. The aerial has an output voltage, an aerial impedance and a length of less than or equal to approximately three meters. An adjustable inductor is coupled to the aerial. A sampler is coupled to the aerial and is adapted to measure the aerial output voltage. A processing unit is coupled to the sampler and to the adjustable inductor.
