摘要： Aspects of the present disclosure are directed to electrochemical approaches for synthesis of platinum-iridium alloys with selected platinum-iridium ratio content and subsequently predetermined mechanical properties and electrochemical impedance properties. Such can provide a simple and cost-effective process for preparing these electrodes, as compared to conventional thin film processing techniques. A three-electrode electrochemical electrodeposition system is described including an electrochemical cell with a working electrode on which the electrodeposited film is deposited, a counter electrode to complete the electrochemical circuit and a reference electrode to measure and control surface potential. Mixed layers of platinum atoms and iridium atoms can be deposited from electrolyte solution onto the working electrode surface to create an electrically conductive surface with material properties related to the composition of the as-deposited film. The mechanical properties and electrochemical properties of the film can be tuned by adjusting the electrodeposition parameters.

摘要： A method for cueing salient regions of an image in an image processing device is provided and includes the steps of extracting three information streams from the image. A set of Gaussian pyramids are formed from the three information streams by performing eight levels of decimation by a factor two. A set of feature maps are formed from a portion of the set of Gaussian pyramids. The set of feature maps are resized and summed to form a set of conspicuity maps. The set of conspicuity maps are normalized, weighted and summed to form the saliency map.

摘要： An image is captured or otherwise converted into a signal in an artificial vision system. The signal is transmitted to the retina utilizing an implant. The implant consists of a polymer substrate made of a compliant material such as poly(dimethylsiloxane) or PDMS. The polymer substrate is conformable to the shape of the retina. Electrodes and conductive leads are embedded in the polymer substrate. The conductive leads and the electrodes transmit the signal representing the image to the cells in the retina. The signal representing the image stimulates cells in the retina.

摘要： Saliency-based apparatus and methods for visual prostheses are disclosed. A saliency-based component processes video data output by a digital signal processor before the video data are input to the retinal stimulator. In a saliency-based method, an intensity stream is extracted from an input image, feature maps based on the intensity stream are developed, plural most salient regions of the input image are detected and one of the regions is selected as a highest saliency region.
