Funny looking object - (with different viewers)
Timo:
On a rainy day I was going through old SI recordings from last summer and found a funny looking object I had earlier dismissed.
The object was about 35 feet from my track and object dimensions are about 5 x 2.5 feet and the height seems to be in the vicinity of 10 inch.
There is a interesting object in the upper left corner too. It seems to be some kind of large reel or roller with loop of cable or heavy rope hanging downward in the image.
Zoomed up version
The Image looks like this on 798ci
and 6x zoomed version
I made also quick comparison how can I find smaller objects from SI Images of different viewers. Below there is some Images and screenshots from common SI viewers of the same weird looking thing.
I am not yet sure what those objects are, but I am gonna find some day out.
Regards,
Timo

Great picture. Looks like 2.0 is on the ball. Chuck
Timo:

Hello Timo
Why is the red marking on the wrong place ::)

Timo:
Hi Gert
The red ellipse shows an estimated target area in HumFinder SI images especially useful if there is number of recordings (and images to be shown) of the same target. The estimation is for taking into account possible GPS error, boat speed, errors in coordinate conversion and calculations.
I guess that the nice structure to the right should have been inside the target ellipse but why it is not? Hmm...
Could it be that the target coordinates are the boat position coordinates and thus estimated target area is shown in the "wrong" place? (Slant correction is taken into account)
Of course there can also be some kind of bug in HumFinder but I haven't noticed this kind of erratic behavior before. In that case could you please sent me the recording (or subrecording) files so I could do some debugging.
By the way, how did you enter the target coordinates to HumFinder? (manually, directly from HumViewer through clipboard, other way...)
Regards,
Timo
ps. Have you tried the object measurement utility yet?
