DISTRIBUTED VIDEO SEARCH WITH EDGE COMPUTING

1 . A method, comprising:

receiving visual data from a camera at a first device, wherein the first device is proximate to the camera;

storing the visual data at a memory of the first device;

receiving a search query at a second device;

transmitting the search query from the second device to the first device; and

determining, at the first device, a relevance of the visual data based on the visual data and the search query.

2 . The method of claim 1 , further comprising:

processing the visual data at the first device with a first inference engine to produce an inference data;

wherein the determined relevance is based on the inference data and the search query.

3 . The method of claim 2 , wherein the inference data is a textual representation of the visual data.

4 . The method of claim 1 , further comprising:

transmitting a search result data from the first device to the second device based on the determined relevance; and

receiving the search result data at the second device.

5 . The method of claim 4 , further comprising:

receiving a third visual data from a third camera at a third device, wherein the third device is proximate to the third camera;

transmitting the search query from the second device to the third device;

determining, at the third device, a relevance of the third visual data based on the third visual data and the search query;

transmitting a search result data from the third device to the second device based on the determined relevance;

comparing, at the second device, the search result data and the third search result data; and

retrieving the visual data or the third visual data based on the comparison.

6 . The method of claim 1 , further comprising:

transmitting the visual data from the first device to the second device based on the determined relevance.

7 . The method of claim 7 , further comprising:

updating an inference engine based on the transmitted visual data.

8 . The method of claim 1 , wherein the first camera is affixed to a first vehicle.

9 . The method of claim 8 , wherein the search query refers to a rarely observed driving scenario.

10 . The method of claim 9 , further comprising:

determining, at the first device, a safety of a driving behavior of a driver of the first vehicle based on the stored visual data.

11 . An apparatus, the apparatus comprising:

a second memory unit;

a second at least one processor coupled to the second memory unit, in which the second at least one processor is configured to:

receive a search query; and

transmit the search query to a first memory unit; and

a first memory unit; and

a first at least one processor coupled to the first memory unit, in which the first at least one processor is configured to:

receive visual data from a proximate camera;

store the visual data at the first memory unit; and

determine a relevance of the visual data at the first device based on the visual data and the search query.

12 . The apparatus of claim 11 , wherein the first at least one processor is further configured to:

process the visual data with a first inference engine to produce an inference data; wherein the determined relevance is based on the inference data and the search query.

13 . The apparatus of claim 11 , wherein the first camera is affixed to a first vehicle.

14 . The apparatus of claim 13 , wherein the search query refers to a rarely observed driving scenario.

15 . The method of claim 14 , wherein the first at least one processor is further configured to:

determine a safety of a driving behavior of a driver of the first vehicle.

16 . An apparatus, the apparatus comprising:

means for receiving visual data from a camera at a first device, wherein the first device is proximate to the camera;

means for storing the visual data at the first device;

means for receiving a search query at a second device;

means for transmitting the search query from the second device to the first device; and

means for determining, at the first device, a relevance of the visual data based on the visual data and the search query.

17 . A computer program product, the computer program product comprising:

a non-transitory computer-readable medium having program code recorded thereon, the program code comprising program code to:

receive visual data from a camera at a first device, wherein the first device is proximate to the camera;

store the visual data to a memory at the first device;

receive a search query at a second device;

transmit the search query from the second device to the first device; and

determine, at the first device, a relevance of the visual data based on the visual data and the search query.

18 . The computer program product of claim 17 , the program code further comprising program code to:

transmit the visual data from the first device to the second device based on the determined relevance.

19 . The computer program product of claim 18 , the program code further comprising program code to:

update an inference engine based on the transmitted visual data.

20 . The computer program product of claim 17 , the program code further comprising program code to:

receive a third visual data from a third camera at a third device, wherein the third device is proximate to the third camera;

transmit the search query from the second device to the third device;

determine, at the third device, a relevance of the third visual data based on the third visual data and the search query;

transmit a search result data from the third device to the second device based on the determined relevance;

compare, at the second device, the search result data and the third search result data; and

retrieve the visual data or the third visual data based on the comparison.
