  • Patent number: 10362215
    Abstract: The present invention discloses a microscopic three-dimensional measurement system and method based on a moving diaphragm. The present invention adds the diaphragm into the existing optical microscopic imaging system to limit light irradiation angle during imaging for reducing the diameter of blur circle, which extends the depth of field and the depth measurement range, so as to achieve the three-dimensional measurement of large-size objects to be measured. Through changing the position of the added diaphragm, two images with different light incident directions are obtained, which is similar to binocular stereo vision, and then the disparity map is used to predict the depth, so as to carry out the 3D scene reconstruction. Since the depth of field of the imaging system is enlarged and the imaging model has certain non-linear characteristics, the present invention uses quadratic function to express the non-linearity, which reduces the measurement error.

    Abstract: A method for evaluating quality of tone-mapping image based on exposure analysis is provided, which explores the exposure properties on each area of the high dynamic range image utilizing the pre-exposure method and divides the high dynamic range image into three parts of an easy overexposed area, an easy underexposed area and an easy natural-exposed area, wherein different quality characteristics are extracted in different areas, which is capable of ensuring that the follow-up quality characteristic extraction is more targeted. The present invention takes the difference of distortion between the tone-mapping image and the conventional image into account, and extracts image characteristics such as the abnormal exposure rate, the underexposed residual energy, the overexposed residual energy and the exposure color index, so as to accurately reflect the quality degradation of the tone-mapping image.

  • Patent number: 9947065
    Abstract: A zero-watermarking registration and detection method for HEVC video streaming against requantization transcoding is provided. To increase an attack-resistance of a registration watermarking, the registration method firstly processes depth values corresponding to respective brightness blocks in a target video streaming with a depth binarization during constructing registration watermarking information through depth features, because the depth binarization well reflects a robustness of the registration watermarking. A first watermarking information matrix including a part of the depth values after the depth binarization is encrypted with a random matrix, so as to increase a safety of the registration watermarking. The registration method directly generates zero-watermarking through the depth features of the video streaming without modifying original carrier information and affecting a watermarking transparency.
