Method and system for frequency coding image data

A computer-implemented method for supplying an algorithm of machine learning for classification of objects included in image data of an individual image of an imaging sensor, the method including the steps:

• supplying first image data of an individual image recorded by an imaging sensor, the first image data having depth values of the individual image that are coded as a whole number or a floating-point number;
• receiving the first image data by an algorithm which frequency codes the depth values of the individual image by a predefined number of periodic functions;
• outputting second image data by the algorithm, the second image data having frequency coded depth values of the individual image
• receiving the second image data output by the algorithm and have frequency coded depth values of the individual image;
• receiving a classification result allocated to an object included in the individual image;
• and
• training of an algorithm of machine learning using the image data and the classification result allocated to the object included in the individual image, by an optimization algorithm, which calculates an extreme value of a loss function.

A system for frequency coding image data of an imaging sensor, comprising:

• an imaging sensor configured to supply first image data of a recorded individual image, the first image data having depth values of the individual image coded as a whole number or as a floating-point number;
• and
• a computing device configured to:
• receive the first image data using an algorithm which frequency codes the depth values of the individual image by a predefined number of periodic functions;
• and
• output second image data using the algorithm, the second image data having frequency coded depth values of the individual image.

A non-transitory computer-readable data carrier on which is stored program code of a computer program for frequency coding of image data from an imaging sensor, the program code, when executed by a computer, causing the computer to perform the following steps:

• supplying first image data of an individual image recorded by the imaging sensor, the first image data having depth values of the individual image that are coded as a whole number or a floating-point number;
• receiving the first image data by an algorithm which frequency codes the depth values of the individual image by a predefined number of periodic functions;
• and
• outputting second image data by the algorithm, the second image data having frequency coded depth values of the individual image.
