4. The frame-processing device of claim 1 , wherein the first region is a generally rectangular-shaped portion of the received first frame, and wherein the second region is a generally rectangular-shaped portion of the received second frame.
5. The frame-processing device of claim 4 , wherein the first and second regions are defined by a left-bound column, a right-bound column, a top-bound row, and a bottom-bound row.
6. The frame-processing device of claim 1 , the set of steps further comprising generating an indication that the pair of the received first and second frames has the particular scene-change/non-scene-change attribute.
7. The frame-processing device of claim 1 , wherein using (i) the first plurality of luma values associated with the first plurality of pixels and (ii) the second plurality of luma values associated with the second plurality of pixels, as the basis to identify the pair of the received first and second frames as having the particular scene-change/non-scene-change attribute comprises identifying the pair of the received first and second frames as having the particular scene-change/non-scene-change attribute responsive to every condition in a condition set being satisfied.
8. The frame-processing device of claim 1 , further comprising using the identified particular scene-change/non-scene-change attribute to facilitate an operation.
9. The frame-processing device of claim 8 , wherein the operation comprises aiding a user in locating a point of interest within the video.
10. A non-transitory computer-readable medium containing instructions that, when executed by the processor, cause performance of a set of steps comprising:
receiving a first frame of video from a video source device;
defining a first region of the received first frame, wherein the first region is associated with a first plurality of pixels of the received first frame;
receiving a second frame of video from the video source device;
defining a second region of the received second frame, wherein the second region is associated with a second plurality of pixels of the received second frame; and
using (i) a first plurality of luma values associated with the first plurality of pixels and (ii) a second plurality of luma values associated with the second plurality of pixels, as a basis to identify the pair of the received first and second frames as having a particular scene-change/non-scene-change attribute.
11. The non-transitory computer-readable medium of claim 10 , wherein the set of steps further comprises generating an indication that the pair of the received first and second frames has the identified particular scene change/non-scene change attribute.
12. The non-transitory computer-readable medium of claim 10 , wherein the set of steps further comprises using the identified particular scene change/non-scene change attribute to aid a user in locating a point of interest within the video.
13. A method comprising:
receiving a first frame of video from a video source device;
defining a first region of the received first frame, wherein the first region is associated with a first plurality of pixels of the received first frame;
receiving a second frame of video from the video source device;
defining a second region of the received second frame, wherein the second region is associated with a second plurality of pixels of the received second frame; and
using (i) a first plurality of luma values associated with the first plurality of pixels and (ii) a second plurality of luma values associated with the second plurality of pixels, as a basis to identify the pair of the received first and second frames as having a particular scene-change/non-scene-change attribute.
14. The method of claim 13 , wherein the received first frame and the received second frame are adjacent frames.
15. The method of claim 13 , wherein the first region is a generally rectangular-shaped portion of the received first frame, and wherein the second region is a generally rectangular-shaped portion of the received second frame.
16. The method of claim 15 , wherein the first and second regions are defined by a left-bound column, a right-bound column, a top-bound row, and a bottom-bound row.
17. The method of claim 13 , further comprising generating an indication that the pair of the received first and second frames has the identified particular scene-change/non-scene-change attribute.
18. The method of claim 13 , wherein using (i) the first plurality of luma values associated with the first plurality of pixels and (ii) the second plurality of luma values associated with the second plurality of pixels, as the basis to identify the pair of the received first and second frames as having the particular scene-change/non-scene-change attribute comprises identifying the pair of the received first and second frames as having the particular scene-change/non-scene-change attribute responsive to every condition in a condition set being satisfied.
19. The method of claim 13 , further comprising using the identified particular scene-change/non-scene-change attribute to facilitate an operation.
