Thank you to Ian, skipper of the Eilidh Anne, and to Bruce for a great #fishingtrip!

@TheMagPi Working on a subsea drop camera system using @Raspberry_Pi Zero 2 in a @BlueRobotics 2” enclosure and @luxonis computer vision for machine learning. Also has a @GoPro 10 for separately recording video

@cheeds06 @braddwyer @roboflow @josephofiowa @wormbotherer @luxonis @HoldernessFIG @CefasGovUK @opencvlibrary For sure Mohamed. I’m still hoping to get some data collection in before my next trip offshore, so will be in touch when I’m ready to start annotate using @roboflow

[John Sperry @HydrographyJohn]

@braddwyer @roboflow @josephofiowa @wormbotherer @luxonis @HoldernessFIG @CefasGovUK @opencvlibrary Although @wormbotherer and @HoldernessFIG I have developed a camera system that puts the model via @luxonis and @roboflow on the device, so give me a shout if ever you want to run some inference directly in the lobster pot!

[John Sperry @HydrographyJohn]

@braddwyer @roboflow @josephofiowa @wormbotherer @luxonis @HoldernessFIG @CefasGovUK @opencvlibrary Thanks Brad. Sadly I don’t work at Cefas anymore so don’t have access to the images. But, perhaps food for thought for those that hold the dataset?

[John Sperry @HydrographyJohn]

@roboflow @josephofiowa @wormbotherer @luxonis @HoldernessFIG @CefasGovUK @opencvlibrary Thanks @roboflow. Didn’t work out too well for predictions. As these are greyscale images would generating a new version and adding an image augmentation step (greyscale) and then retrain the model?

[John Sperry @HydrographyJohn]

@roboflow @josephofiowa @wormbotherer @luxonis @HoldernessFIG @CefasGovUK @opencvlibrary @wormbotherer and @HoldernessFIG a quick test with images you’ve posted on Twitter. Not bad considering most of the images in the training set are lobsters on a plate. Perhaps worth some further investigation?

[Roboflow @roboflow]

@HydrographyJohn @josephofiowa @wormbotherer @luxonis @HoldernessFIG @CefasGovUK @opencvlibrary just in case you're still interested in building that lobster model :)

How are we supporting #SDG14 life below water?

Overfishing and bycatch are huge global problems with few proven solutions. We are developing #ocean technology that empowers #fishermen to catch more of their target species sustainably 🐟

We got 🦞🦞! A camera system several years in the making and against global silicone and Raspberry Pi shortages, we're on the go with our Lobstercam for the @HoldernessFIG @CefasGovUK @ICITOrkney @Fisheriesbangor #FISP data collection.
@HydrographyJohn look! 😃

[John Sperry @HydrographyJohn]

@wormbotherer @HoldernessFIG @CefasGovUK @ICITOrkney @Fisheriesbangor A great set of images. A lobster - check, in a pot - check, in very low light conditions - check! Excellent news for the project. Might be worth a look at the RTC though, as the overlay date / time stamps look a little wrong.

This #BellLetsTalk Day, take a moment to check in with your mental health. Giving yourself a few seconds to breathe in and out can be a great way to focus - try following along with these tides.

As signatories of the UK Squirrel Accord, we’re committed to recovering red squirrel populations.

Between 12-2pm, @SquirrelAccord will be making #RedSquirrels the topic of conversation, to raise awareness of these threatened animals.
Use #RedSquirrelAppreciationDay to take part.
