METHOD FOR PROCESSING IMAGES OF SPECKLE STRUCTURES FROM SCATTERED LASER RADIATION ON FERROFLUID NANOPARTICLES ORIENTED IN A MAGNETIC FIELD Russian patent published in 2021 - IPC G01N21/47 G06T5/00 

FIELD: checkout technique.

SUBSTANCE: invention relates to the field of checkout technique and concerns a method for processing images of speckle structures. The method consists in processing images of speckle structures formed by nanoparticles of ferrofluid placed in a magnetic field formed in laser radiation transmitted through a cell with ferrofluid or reflected from speckle structures. Images are recorded using a camera without focusing optics with autofocus disabled and processed using the RGB color space. To exclude the influence of the intensity of channels B and G associated with the hardware completion of the computer image to improve its perception by the eye, the brightness, color gamut and shades are aligned to the average value. The remaining part of the light noise is compensated by adjusting the RGB channels. In the case of using high-intensity laser radiation to compensate for noise associated with the hardware completion of the computer on the G and B channels, the curves of the RGB channels are adjusted. At the final stage of processing, the choice of the color radiation intensity from the pixel sequence number is implemented.

EFFECT: improving of the obtained images quality.
