Abstract
An apparatus and a method implemented in a computer system for obscuring a first region of an image composed by a plurality of pixels. The method comprising obtaining a mask, the mask defining an obscurity level for each pixel in the first region of the image, and obscuring pixels in the first region of the image based on the mask's obscurity level for each pixel.
Claims17
A method implemented in a computer system for producing a masked image having an obscured first region, the method comprising:
- capturing, by a camera, an image composed by a plurality of pixels;
- analyzing the content of the image;
- creating a privacy mask by applying one or more rules to the results of the analysis, the rules defining a gradual transition around the edges of a first region of the image to create a smooth transition between masked and unmasked regions of the image and thereby obtaining the privacy mask defining an obscurity level for each pixel in the first region of the image on a pixel-by-pixel basis;
- and
- applying the privacy mask to the image, thereby producing the masked image having obscured pixels in the first region of the masked image based on the privacy mask's obscurity level for each pixel.

A system for producing a masked image having an obscured first region, the system comprising:
- a processor configured to receive at least an image composed by a plurality of pixels from a camera;
- the processor configured to analyze the content of the image;
- the processor configured to create a privacy mask by applying one or more rules to the results of the analysis, the rules defining a gradual transition around the edges of a first region of the image to create a smooth transition between masked and unmasked regions of the image and obtaining the privacy mask defining an obscurity level for each pixel in the first region of the image on a pixel-by-pixel basis;
- and
- the processor configured to apply the privacy mask to the image, producing the masked image having obscured pixels in the first region of the masked image based on the privacy mask's obscurity level for each pixel.
