Embodiment Construction

[0050] figure 1 A flow chart of a computer-implemented method for frequency encoding image data of an imaging sensor according to a preferred embodiment of the present invention is shown.

[0051] The imaging sensor is preferably installed in the motor vehicle. Alternatively, imaging sensors can be used for traffic monitoring in public spaces, for example in the region of road intersections. Still alternatively, the imaging sensor can be arranged in the building, for example in the entrance area of ​​the building, for environment monitoring.

[0052] The imaging sensor is preferably an environmental sensor of the motor vehicle. Alternatively, the imaging sensor can be formed, for example, by an interior sensor installed in the motor vehicle or an environment sensor installed in a public space and / or on or in a building.

[0053] The method comprises providing S1 first image data BD1 of the individual images E recorded by the imaging sensor 10 , wherein these first image dat...

Abstract

Methods and systems for frequency coding of image data. The invention relates to a computer-implemented method for frequency encoding image data of an imaging sensor, comprising: providing first image data of a single image recorded by the imaging sensor, where the first image data has depth values of the single image encoded in an integer or as a floating-point number; receiving the first image data by means of an algorithm which frequency encodes the depth values of the individual image by means of a predetermined number of periodic functions; and outputting second image data by an algorithm, wherein the second image data has the frequency encoded depth values of the single image. The invention also relates to a computer-implemented method for providing a machine learning algorithm to classify an object contained in image data of a single image of an imaging sensor. The invention also relates to a system, a computer program and a computer-readable data carrier for frequency encoding image data of an imaging sensor.

Description

technical field [0001] The present invention relates to a computer-implemented method for frequency encoding image data of an imaging sensor. [0002] The invention also relates to a computer-implemented method for providing a machine learning algorithm for classifying objects contained in image data of a single image of an imaging sensor. [0003] The invention also relates to a system for frequency encoding image data of an imaging sensor. Background technique [0004] Image data processed with artificial neural networks are usually stored in a grid in which individual values, ie pixels, contain image information. This information is usually a decimal value or a floating point value. All common methods for image classification, such as ResNet (residual neural network) use this data representation. [0005] The depth image as produced by the depth camera is also processed by the artificial neural network in this representation. [0006] Information is evaluated in depth...
