  • Publication number: 20220147763
    Abstract: A recognition system and an image augmentation and training method thereof are provided. The image augmentation and training method of a recognition system includes the following steps. A plurality of image frames are obtained, wherein each of the image frames includes an object pattern. A plurality of environmental patterns are obtained. The object pattern is separated from each of the image frames. A plurality of image parameters are set. The image frames, based on the object patterns and the environmental patterns, are augmented according to the image parameters to increase the number of the image frames. A recognition model is trained using the image frames.

  • Publication number: 20210365662
    Abstract: A fingerprint recognition method is provided. The method includes obtaining a plurality of fingerprint images by sensing a finger of a user, respectively calculating geometric center points corresponding to the fingerprint images, and calculating positions and offsets of the fingerprint images according to the geometric center points. The method also includes filling signals in the fingerprint images into a part of pixels in a pixel array according to the positions and the offsets of the fingerprint images, and obtaining signals of other pixels in the pixel array by inputting the signals filled in the part of pixels in the pixel array into an artificial intelligence engine. The method further includes generating a candidate fingerprint image and recognizing a user based on the candidate fingerprint image.

  • Patent number: 9529124
    Abstract: An optical film structure includes a first substrate having a first surface and a second surface, an optical component includes a micro-lens array and disposed on the first surface of the first substrate, a micro-lens array including a plurality of micro-lens units each of which has a round concentrated area with a projected radius R formed on the first surface, a planarization layer disposed on the optical component, a light absorbing layer disposed on the planarization layer and including a plurality of light absorbing units each of which has a width W. Light incident from the second surface of the first substrate and passing through the micro-lens array is focused on the light absorbing units. The micro-lens array and the planarization layer have a difference in refractive index greater than or equal to 0.2; and W is less than or equal to R/2.
