agribot2 commented 5 years ago

Find-object crashes about 1 in 3 times on windows 7 laptop.

version is 0.6, opencv 3.0.0 with non-free. Installed on a 64 bit Windows 7, on a Sony VPCF1 type laptop, running Intel i7 processor

Find-Object was installed by downloading and running the win-64 exe installer file. The find-object.exe file is date 10/07/2015, size 118KB

example of operation;- start up Find-Object by clicking on the above .exe file press space bar for default camera (laptop) add object from file crash

It also crashes about 1 in 5 times after ...delete object...

There is a version 0.6.2 here : https://github.com/introlab/find-object/releases You can also try the latest version (not officially released) here: https://ci.appveyor.com/project/matlabbe/find-object/branch/master/artifacts

As suggested, I've replaced version 0.6 with version 0.6.2. The defect has not occurred after several hours. I'll close this issue.

Many thanks for your prompt and effective help.

Hi Thanks for your very helpful and quick reply.

I'm very impressed with the find-object tool. I think many more novices and new-comers could find it interesting, if there was more tutorial type material about it available on the web.

let me explain... I'm a new comer to computer vision, image classification and object detection, etc. I've studies opencv, and learned from various sites, such as https://www.pyimagesearch.com/2018/09/10/keras-tutorial-how-to-get-started-with-keras-deep-learning-and-python/, etc.

To understand how to use Find-Object ... I installed it and used it ! I'm impressed. Then ...

I looked at the various sites, including ;- https://github.com/introlab/find-object/wiki , https://introlab.github.io/rtabmap/ , https://husarion.com/tutorials/ros-tutorials/4-visual-object-recognition/ , etc.

But ... there is a lack of information about many of its functions and their operation.

For example, there does not seem to be any explanation about what the " camera from directory of images " does. Of course it becomes fairly clear by just using that function, and other simpler functions. But often novices like me will be struggling with the question ;- is it supposed to do that ? What is it doing now ? Not all it's functions are self-explanatory to new-comers.

If there were more tutorials, I'm sure many more learners would use the tool and it's popularity would increase. Many would then be able to get into the details ( setting parameters, etc ) and your teams reputation would be greatly increased.

While I understand that basic introductory information takes time and is often tedious to the experts, well, .... we all had to start at some time !

With Regards,

Robert Agribot

Hi Robert,

Thank you for for your support and your suggestions. There are indeed only a limited number of tutorials on Find-Object by lack of time (I am more involved on RTAB-Map project right now) and it was a tool made at the beginning for people who already played a little with OpenCV's feature detection a priori. That project evolved over time to be more user friendly, even into an application that can be used directly as interface to other applications (like with TCP/IP support). I see that many new comers can learn what OpenCV's feature detection can do with Find-Object. I use it also often when I need to tune visual feature parameters for other projects.

I am supposed to come back to Find-Object and add new features in the near future, I'll see if I can add more details to this introductory tutorial, in particular the other options we see in the menus.

Regards, Mathieu
