  • Video encoding and decoding method of mitigating data losses in an encoded video signal transmitted through a channel
    Patent number: 6909450
    Abstract: In the case of loss of data in an encoded video image cut up into slices and associated with an encoded video signal, referred to as current image, the video encoding and decoding method according to the invention allow decoding of the slices of said current image that are not affected by the loss of data, even if the image header of said current image has been lost.

  • Digital method of modifying an image contrast so as to retain imaging of small objects
    Patent number: 4999711
    Abstract: The method has for its object to enhance the contrast of an image, more specifically a low-contrast infrared image. The method is used in a system for putting the method into effect, more specifically an infrared camera operating in real time. The output image is structured with the aid of a transformation function (FI) one part of which (RCI) transforms the contrast of the warm points; the output histogram (HSI) has a higher contrast than the input histogram (HE). The point GO is determined for each image as a function of the characteristics of the input histogram (HE).
