Hi.

For the last 50 pictures I got 15 times the message:
Error! You've already submitted this image. Please reload and try again.

This corresponds to 38% and happens al the time. It is really frustrating that the message comes at the end when I click on "submit". So I draw al lot of boxes for nothing. Please optimize the algorithm for reviewing images.

Now:
1. load images
2. fit the boxes
3. submit
4. check if the image already reviewed
5. error message when already reviewed

Better:
1. check if the image already reviewed
2. load only not reviewed images
3. fit the boxes
4. submit
Or
1. Load images
2. check if the image already reviewed
3.1 skip automatically if already reviewed
3.2. or show the error message and skip manually if automatically is not possible
4. …

Thanks
Tom

I will whole-heartedly second this request. The problem appears to get worse the more images you have reviewed. By this point I would be very happy to get 35 valid images of 50, it just doesn't happen. I have had the same picture displayed in the same short session (and it had already been viewed before so it was an error both times).

On the plus side, I appear to still get credit for the errors ;-)

However, I would feel more productive if I wasn't repeating work already done.

Cheers,
g

Small typing error. It were 19 of 50 reviews. I counted 50 to get an example.
And yes:

The problem appears to get worse the more images you have reviewed.

I should add, this does not occur in the UAV project since that is an already ordered set of images, only the other two image viewing projects.

All, will be looking into this issue over the next couple days and report back. Thanks for the heads up!

Tom, can you confirm that it's not happening in the UAV images, but in the trailcam ones only? Help me nail down where in the code to look, though I'll be reviewing both sets of code.

No. Sorry.
I never reviewed UAV images.

Tom and Gibson, I've done an overhaul on the code for the trailcam images. I've gone through about 100 images without any issues on my end, but can you please confirm that it's working as expected now?

Thanks for your help!

Just did 20-odd images from the Eider project with no errors encountered. I'll do some more later but it is looking very good from my end. :-)

Hi Marshall

I reviewed 50 images of Lesser Snow Goose and 50 images of Common Eider and did not got an image twice. I also reviewed a lot of UAS images the last days and never got an image twice.

For me it works perfect now.

Thanks
Tom
