Embedded image quality stamps
In an image generation and rendering system, a quality stamp indicative of image fidelity is embedded in image data units resulting from image data compression/encoding. At decoding, the image quality stamp is captured and when the decoded image is rendered, a fidelity indicator is displayed along with the image.
1. A method, comprising:
accessing image data representative of an image, the image data being stored in a database communicatively coupled to an imaging apparatus with which the image data was generated;
encoding the image data for transmission to a user, wherein the encoding results in a plurality of compressed image data units; and
embedding in each of the compressed image data units a quality stamp indicative of a fidelity level of a corresponding object or region in the image that is to be presented on a display.
2. The method of claim 1 , further comprising storing the image data in a buffer.
3. The method of claim 1 , wherein the encoding comprises encoding the image data in accordance with a predetermined protocol.
4. The method of claim 3 , wherein the predetermined protocol is one of MPEG, H.264, wavelet or run-length encoding.
5. The method of claim 1 , further comprising embedding the quality stamp in a header portion of at least one of the compressed image data units.
6. The method of claim 1 , further comprising displaying indicia, based on the quality stamp, indicative of a fidelity level of the image being presented on the display.
7. The method of claim 6 , further comprising rendering a boundary around at least a portion of a region of interest of the image to indicate the level of fidelity.
8. The method of claim 6 , further comprising rendering a background color change, based on the quality stamp, indicative of a fidelity level of the image being presented on the display.
9. The method of claim 6 , further comprising rendering a textual annotation, based on the quality stamp, indicative of a fidelity level of the image being presented on the display.
10. The method of claim 1 , further comprising switching among rendered indicia indicative of a fidelity level of the image being presented on the display.
11. The method of claim 1 , further comprising detecting the quality stamp during a decoding process.
12. The method of claim 1 , further comprising receiving a request for higher resolution imagery.
13. The method of claim 12 , further comprising:
accessing the image data representative of the image; and
at least one of:
re-encoding, at least a portion of the image data at a resolution level higher than a prior resolution level, for transmission to the user, or
transmitting selectively pre-encoded data units upon user requests.
14. The method of claim 13 , further comprising updating a displayed fidelity indicator in accordance with the quality stamp embedded in the compressed data units resulting from the re-encoding.
15. A system, comprising:
an encoder configured to receive image data and to encode the image data in accordance with a predetermined standard, and further configured to embed in at least selected packets resulting from encoding a quality stamp that is indicative of a level of fidelity with which the image data is encoded.
16. The system of claim 15 , further comprising a database in which the image data is stored.
17. The system of claim 16 , further comprising an imaging apparatus configured to be in communication with the database that generates the image data.
18. The system of claim 17 , wherein the imaging apparatus is a medical imaging apparatus.
19. A system, comprising:
a decoder and a display, wherein the display is configured to render an image from encoded image data units received and decoded by the decoder, the decoder is further configured to decode a quality stamp embedded in selected encoded image data units, the quality stamp being indicative of a level of fidelity with which the image data was encoded.
20. The system of claim 19 , wherein the display is configured to render a fidelity indicator that indicates a level of fidelity in accordance with the quality stamp.
21. The system of claim 19 , wherein the individual encoded image data units are individual packets.
22. The system of claim 19 , further comprising a user interface that is configured to receive, explicitly or implicitly, a request for a higher resolution or a lossless image.
23. The system of claim 19 , further comprising means for storing as an archive a rendered image along with its indicated level of fidelity.
24. Logic encoded in a non-transitory computer-readable medium for execution and when executed operable to:
access image data representative of an image;
encode the image data for transmission to a user, wherein encoding results in a plurality of compressed image data units; and
embed in each of the compressed image data units a quality stamp indicative of a fidelity level of a corresponding object or region in the image that is to be presented on a display.
