Abstract

An electronic device and a method of determining brightness gradients of an electronic device are provided. The electronic device includes a memory configured to store a digital image, and a processor configured to process the digital image, wherein the processor is configured to recognize at least one object of the digital image, to determine a descriptor used to recognize the object, to determine the descriptor by using at least one of a location, a direction, and a scale of a feature point on the digital image, to determine brightness gradients of pixels located within an area surrounding the feature point, and to determine the brightness gradients of the pixels based on two or more non-orthogonal fixed directions.

Description

technical field [0001] The present disclosure relates to electronic devices and methods for determining descriptors thereof. More particularly, the present disclosure relates to an electronic device and a method for determining a descriptor in which a descriptor for recognizing an object on image data can be efficiently calculated. Background technique [0002] Augmented reality is a technique for showing the real world viewed by the user with eyes superimposed on virtual objects. Augmented reality is also referred to as mixed reality (MR), since augmented reality combines the real world with a virtual world with additional information and shows this combination in real time as one image. Although augmented reality, which supplements the real world with a virtual world, uses a virtual environment generated through computer graphics, the real environment plays a leading role in augmented reality. Computer graphics services are used to additionally provide information necess...
