Method of highlighting an object of interest in an image or video

1. A method of highlighting an object of interest in an image, the method comprising:

providing a digital image;

receiving data representing one or more bounding boxes determined for objects in the digital image;

determining, by selecting one of the one or more bounding boxes, a region of interest, inside the digital image, covering an object of interest having a person identifier, wherein the person identifier is a feature, characteristic or object from which a person identity can be uniquely identified;

masking all image data in the digital image in a surrounding area to the region of interest;

within the region of interest, determining a region of exclusion covering an object of exclusion in the digital image having another person identifier; and

forming an output image comprising image data from the region of interest, wherein the region of exclusion thereof is masked, and comprising the masked image data of the surrounding area.

2. The method according to claim 1 , wherein the surrounding area corresponds to the rest of the digital image.

3. The method according to claim 1 , wherein the image data is masked by manipulation of image data from the digital image.

4. The method according to claim 1 , wherein the object of interest is a human.

5. The method according to claim 4 , further comprising receiving an identity of a human, and wherein the act of determining the region of interest is performed based on the received identity.

6. The method according to claim 1 , wherein the act of determining a region of interest or determining a region of exclusion comprises executing an object detection algorithm on the digital image.

7. The method according to claim 1 , wherein the person identifier comprises a face, a license plate, or an id tag.

8. A method of highlighting an object of interest in a video sequence, the method comprising:

providing a video sequence comprising digital images,

for each image of a selection of digital images from the video sequence, applying the method according to claim 1 , and

forming an output video sequence comprising the output images.

9. A method of highlighting an object of interest in a video sequence, the method comprising:

providing a video sequence comprising digital images;

for a first image selected from the video sequence,

receiving data representing one or more bounding boxes determined for objects in the first image, and

determining, by selecting one of the one or more bounding boxes, a first region of interest, inside the first image, covering an object of interest having a person identifier, wherein the person identifier is a feature, characteristic or object from which a person identity can be uniquely identified;

for a second image selected from the video sequence,

receiving data representing one or more bounding boxes determined for objects in the second image, and

determining, by selecting one of the one or more bounding boxes, a second region of interest, inside the second image, covering the object of interest;

for temporally intermediate images located between the first image and the second image in the video sequence,

determining respective regions of interest by interpolation between the first region of interest in the first image and the second region of interest in the second image;

for each digital image of the first image, the second image, and the temporally intermediate images,

masking all image data in the digital image that are in a surrounding area to the digital image's respective region of interest,

within the respective region of interest, determining a region of exclusion covering an object of exclusion in the digital image having another person identifier, and

forming an output image comprising image data from the respective region of interest, wherein the region of exclusion thereof is masked, and comprising the masked image data of the surrounding area; and

forming an output video sequence comprising the output images.

10. A non-transitory computer-readable storage medium with instructions adapted to carry out a method when executed by a device having processing capability, the method comprising:

providing a digital image;

receiving data representing one or more bounding boxes determined for objects in the digital image;

determining, by selecting one of the one or more bounding boxes, a region of interest inside, the digital image, covering an object of interest having a person identifier, wherein the person identifier is a feature, characteristic or object from which a person identity can be uniquely identified;

masking all image data in the digital image in a surrounding area to the region of interest;

within the region of interest, determining a region of exclusion covering an object of exclusion in the digital image having another person identifier; and

forming an output image comprising image data from the region of interest, wherein the region of exclusion thereof is masked, and comprising the masked image data of the surrounding area.

11. A device arranged to highlight a region of interest in a digital image, the device comprising:

a detector arranged to

receive data representing one or more bounding boxes determined for objects in the digital image,

determine, by selecting one of the one or more bounding boxes, a region of interest, inside the digital image, covering an object of interest having a person identifier, wherein the person identifier is a feature, characteristic or object from which a person identity can be uniquely identified, and

within the region of interest, determine a region of exclusion covering an object of exclusion in the digital image having another person identifier; and

a processor arranged to

mask all image data in the digital image in a surrounding area to the region of interest, and

form an output image comprising image data from the region of interest, wherein the region of exclusion thereof is masked, and comprising the masked image data of the surrounding area.

12. The device according to claim 11 , arranged in a video card of a video management system.
