3.3.1. --vid-in-path
- Deprecated
--in-video
- Type
STRING
- Default
[empty]
- Example
--vid-in-path ~/Videos/meteors.mp4
Input video path (supports also a path to a sequence of images
path/basename_%05d.jpg
).
3.3.2. --vid-in-start
- Deprecated
--fra-start
- Type
INTEGER
- Default
0
- Example
--vid-in-start 12
First frame id (included) to start the detection in the video sequence.
3.3.3. --vid-in-stop
- Deprecated
--fra-end
- Type
INTEGER
- Default
0
- Example
--vid-in-stop 42
Last frame id (included) to stop the detection in the video sequence. If set to
0
, read entire video.
3.3.4. --vid-in-threads
- Deprecated
--ffmpeg-threads
- Type
INTEGER
- Default
0
- Example
--vid-in-threads 1
Select the number of threads to use to decode video input (in ffmpeg
). If
set to 0
, ffmpeg
chooses the number of threads automatically.
3.3.5. --trk-path
- Deprecated
--in-tracks
- Type
STRING
- Default
[empty]
- Example
--trk-path tracks.txt
The tracks file corresponding to the input video (generated from
fmdt-detect
). See Section 3.1.1 for the description of the
expected text input format.
3.3.6. --trk-bb-path
- Deprecated
--in-bb
- Type
STRING
- Default
[empty]
- Example
--trk-bb-path bb.txt
The bounding boxes file corresponding to the input video (generated from
fmdt-detect
). See Section 3.2.9 for the description of the
expected text output format.
3.3.7. --trk-id
- Deprecated
--show-id
- Type
BOOLEAN
- Example
--trk-id
Show the object ids on the output video and frames. Requires to link with OpenCV
library (-DFMDT_OPENCV_LINK
CMake option, see
Section 2.2.1).
3.3.8. --trk-nat-num
- Deprecated
--show-id
- Type
BOOLEAN
- Example
--trk-nat-num
Natural numbering of the object ids, work only if --trk-id
is set.
3.3.9. --trk-only-meteor
- Deprecated
--only-meteor
- Type
BOOLEAN
- Example
--trk-only-meteor
Show only meteors.
3.3.10. --gt-path
- Deprecated
--in-gt
- Type
STRING
- Default
[empty]
- Example
--gt-path gt.txt
File containing the ground truth. Ground truth file gives objects positions over time. Here is the expected text format of a line:
{otype} {fbeg} {xbeg} {ybeg} {fend} {xend} {yend}
{otype}
can be meteor
, star
or noise
.
{fbeg}
and {fend}
stand for frame begin and frame end.
{xbeg}
and {ybeg}
stand for \(x\) and \(y\) coordinates of the
frame begin.
{xend}
and {yend}
stand for \(x\) and \(y\) coordinates of the
frame end.
{fbeg}
, {xbeg}
, {ybeg}
, {fend}
, {xend}
, {yend}
are
positive integers. Each line corresponds to an object and each value is
separated by a space character.

STRING
- Default
[empty]
- Example
--vid-out-path sky.mp4

path/basename_%05d.jpg
) with meteor tracking colored rectangles (BBs).
If --gt-path
is set then the bounding rectangles are red if false positive
meteor and green if true positive meteor.
3.3.12. --vid-out-id
- Type
BOOLEAN
- Example
--vid-out-id
Show the frame id number on each frame (on the bottom left corner of the image).
Requires to link with OpenCV library (-DFMDT_OPENCV_LINK
CMake option,
see Section 2.2.1).
