receive, from the server device, location information for at least one portion of the original image that contains at least one content item for the physical document, the location information being based on the document type;

extract, based on the location information, the at least one portion of the original image to generate at least one extracted portion of the original image;

send a second request to the server device for the at least one content item, wherein the second request comprises the at least one extracted portion of the original image; and

responsive to receiving the at least one content item from the server device, provide the at least one content item for display by a client device.

12. The computing apparatus of claim 11 , wherein the location information comprises bounding box coordinates for the at least one portion of the original image that contains the at least one content item.

13. The computing apparatus of claim 12 , wherein to the processing device is further to:

receive, from the server device, the document type for the physical document;

determine, based on the document type, the at least one content item for the document; and

send a third request to the server device for the bounding box coordinates for the at least one content item.

14. The computing apparatus of claim 11 , wherein to create the reduced file the processing device is to:

transform the original image by performing at least one of a color to grayscale conversion, a color to black and white conversion, a data compression operation, an image resolution reduction operation, or a binarization operation.

15. The computing apparatus of claim 11 , wherein to create the reduced file the processing device is to:

select a fragment of the original image as the reduced file.

16. The computing apparatus of claim 11 , wherein the at least one extracted portion of the original image is a same resolution as the original image.

17. The computing apparatus of claim 11 , wherein the processing device is further to:

provide the at least one content item to at least one of an application executing on the client device, or an application executing on the server device.

18. The computing apparatus of claim 11 , wherein the processing device is further to:

19. The computing apparatus of claim 11 , wherein the original image comprises a video stream of a plurality of image frames, and wherein the location information comprises information identifying at least one frame of the plurality of image frames, and wherein the at least one portion of the original image comprises the at least one frame.

20. The computing apparatus of claim 11 , wherein the second request is sent to a second server device; and the at least one content item is received from the second server device.

21. A non-transitory computer readable storage medium, having instructions stored therein, which when executed by a processing device of a client device, cause the processing device to perform operations comprising:
