    Abstract: A computer system for identifying coating colors using a digital image comprises one or more processors and one or more computer-readable media having store thereon executable instructions that when executed by the one or more processors configure the computer system to perform various actions. For example, the computer system can receive, through the network connection, a user-provided digital image of a vehicle. The computer system can also identify, with an image processing module, one or more vehicle characteristics within the user-provided digital image. Further, the computer system can identify at least one coating color based on the one or more vehicle characteristics.

    Abstract: Embodiments of the invention provide a method and system that allows parameters of a desired target image to be determined from hyperspectral imagery of scene. The parameters may be representative of various aspects of the scene being imaged, particularly representative of physical properties of the scene. For example, in some medical imaging contexts, the property being imaged may be blood perfusion or oxygenation saturation level information per pixel. In one embodiment the parameters are obtained by collecting lower temporal and spatial resolution hyperspectral imagery, and then building a virtual hypercube of the information having a higher spatial resolution using a spatiospectral aware demosaicking process, the virtual hypercube then being used for estimation of the desired parameters at the higher spatial resolution. Alternatively, in another embodiment, instead of building the virtual hypercube and then performing the estimation, a joint demosaicking and parameter estimation operation is performed to obtain the parameters. Various white level and spectral calibration operations may also be performed to improve the results obtained. While establishing functional and technical requirements of an intraoperative system for surgery, we present iHSI system embodiments that allows for real-time wide-field HSI and responsive surgical guidance in a highly constrained operating theatre. Two exemplar embodiments exploiting state-of-the-art industrial HSI cameras, respectively using linescan and snapshot imaging technology, were investigated by performing assessments against established design criteria and ex vivo tissue experiments. We further report the use of one real-time iHSI embodiment during an ethically-approved in-patient clinical feasibility case study as part of a spinal fusion surgery therefore successfully validating our assumptions that our invention can be seamlessly integrated into the operating theatre without interrupting the surgical workflow.

    Abstract: Un Terminal communiquant comprend une unité centrale (C), une mémoire, un dispositif d'affichage (ET), un dispositif d'entrée (ET), une caméra (CA) opérant dans le visible, un circuit de communication sans fil, un capteur acoustique et un transducteur acoustique. Il est également prévu un capteur d'images (IM) dans le domaine non visible, distinct de la caméra et générant des images de pixels dans le domaine non visible au-delà de la gamme de sensibilité spectrale du silicium. Ce capteur comprend une matrice de cellules photosensibles au rayonnement dans le domaine non-visible, prévues sur un substrat non-silicium accouplé à un circuit de lecture sur substrat silicium, un filtre passe-bande (130; 140n; 150n) opérant dans le domaine non-visible et interposé sur le trajet du rayonnement. Le terminal est configuré pour réaliser une prise de vues d'une scène avec plusieurs phases d'exposition de la matrice pour une pluralité d'axes de visée différents du capteur, au moins une partie des pixels recevant un rayonnement issu d'une même partie de la scène dans des bandes de longueurs d'onde différentes lors des différentes phases d'exposition. Le terminal comprend en outre un circuit de traitement apte à combiner entre elles les images capturées lors de ces phases, de manière à ce qu'à une même cellule photosensible de la matrice puissent être affectées au moins deux valeurs de luminosité dans l'espace dans au moins deux bandes spectrales différentes avec une résolution supérieure à la résolution intrinsèque du capteur.
