Abstract: A method for recognizing characters in an image of a document having at least one alphanumeric field. The method includes the steps of enhancing an image contrast to highlight the characters in the image; detecting contours of objects in the image to create a mask that highlights the characters; segmenting the image using a tree with connected components and applying the mask thereto in order to extract the characters from the image; performing a character recognition on the extracted objects. A device for implementing the method.

Abstract: A method for recognizing characters in an image of a document having at least one alphanumeric field. The method has the steps of: segmenting the image to identify objects therein; defining a bounding box around each object; making multiple successive selections based on different descriptors and dividing the bounding boxes into a plurality of cells for each of which a texture descriptor is determined as a gradient oriented histogram; performing character recognition on the finally selected bounding boxes. A device for implementing the method.

Abstract: An electrostatic spraying installation for conductive liquid coating product comprises a circuit for distributing fluids including the conductive coating product. At least one coating product sprayer is fed by this circuit and is connected to a variable or interruptible high voltage supply. At least one insulated auxiliary coating product storage tank is adapted to be raised to the high voltage. The installation includes at least one rinsing product supply and at least one compressed air supply. The circuit comprises at least one mobile member isolator connected between two parts of the distribution circuit to isolate the upstream circuit part from the high voltage. The installation comprises an arrangement of valves on the upstream and downstream sides of the isolator connected to the rinsing product supply and to the compressed air supply for cleaning and purging the isolator before it is opened each time.
