Abstract: A computer-implemented technique can receive, at a computing device including one or more processors, a plurality of photos. The technique can extract quality features and similarity features for each of the plurality of photos and can obtain weights for the various quality features and similarity features based on an analysis of a reference photo collection. The technique can generate a quality metric for each of the plurality of photos and can generate a similarity matrix for the plurality of photos by analyzing the various quality features and similarity features and using the obtained weights. The technique can perform joint global maximization of photo quality and photo diversity using the quality metrics and the similarity matrix in order to select a subset of the plurality of photos having a high degree of representativeness. The technique can then store the subset of the plurality of photos in a memory.

Abstract: Systems and methods for diagnosing epithelial neoplasia and other conditions includes, in a representative embodiment, providing the human eyes with a filter to observe the autofluorescence of a tissue sample. Using optimized wavelengths from a filtered light source, a sample is illuminated. The radiation from the sample is filtered to enhance the contrast between a normal sample and a diseased sample observable by the human eye.

Abstract: Coffee bean particles placed in a water permeable packet sized to fit between a cheek and gum is disclosed. Such a product can overcome many difficulties for those who consume coffee. For example, if an individual is away from civilization or simply does not have hot water or a coffee maker and has a desire to consume coffee, the individual can place the packet into ones mouth and enjoy coffee as if drinking a cup of coffee.

Abstract: Methods and apparatus for depth-resolved spectroscopy. A ball lens may be used to redirect light from a fiber-optic probe so that the light intersects the detection region of a collection probe in a specific depth layer of the specimen. A fiber-optic probe may comprise a collection fiber proximal to a central axis of a ball lens and a pair of illumination fibers distal to the central axis.
