Right: input plants, left: colour based plant segmentation using Gaussian Mixture Models I’ve won a grant to investigate the dynamic modelling of plant growth using computer vision. The plan is that we’re going to grow a load of Arabidopsis (that’s the plant in the picture above), under time-lapse cameras, and work out where the leaves are, and which leaves cover up which other leaves. Essentially, we’ll use the time-series of images as the plant grows to infer the 3D structure of the plant. Cool, eh? If you might be interested in this kind of project, and you can do computing and machine learning, then getRead More →

The International Workshop on Image Analysis Methods for the Plant Sciences will be held this year in Aberystwyth. The workshop is aimed at computer vision and image processing people working in the plant sciences, and plant science people doing work with images. I’m the co-chair, along with Marie Neal from the National Plant Phenomics Centre, Andrew French from Nottingham Computer Science and Susie Lydon from Nottingham’s Centre for Plant Integrative Biology. Key facts Abstract submission 1 Aug. Abstracts should be 2 pages max, PDF, submitted via CMT the conference submission site. Registration deadline 1 Sep. You can register online via EventBrite. Conference dates 15-16 Sep.Read More →

For the last two weeks I’ve had a work experience student in working on AppInventor stuff. When she started, she’d never done any coding before, so I set her off on updating the materials for the AppInventor Family Fun Day. … and the materials are now ready Check the Family Fun Day page for fully updated materials, ready for AppInventor 2. Free, creative commons licensed one-day android programming workshop, now fully up to date again. AND she got an app on Google Play Check out PieSplat! A custard pie app where you can change the target image, and play either Whack-a-mole style or by flingingRead More →

This post is a collection of all the blogs, photos and articles I’ve found about the BCSWomen Lovelace Colloquium 2014. If I’ve missed anything – leave a comment or drop me an email and I’ll add it. Photos! The photos from the day are now available on Flickr. Check them out, Silvia took some great pictures. Students have been blogging about the day Michelle Brown from De Montfort wrote on her own blog but also had a guest post on Computer Weekly Charlotte Godley from Hull Uni (also a prizewinner) wrote a post on her own site and on Computer Weekly Polina Stoyanova from GreenwichRead More →

On Wednesday 16th, I was in Reading for the BCSWomen Lovelace Colloquium. This is a national one-day conference for women undergraduates, which I started back in 2008 and which is now in its 7th year. This long and rambling blog post with pictures is my brain-dump report of the day. Hope you find it interesting in some way – I thought the day itself was AMAZING (but then again I would say that). As ever on “BCSWomen Lovelace Day” I woke up stupidly early, and the moment I realised the date I was wide awake. So I did a bit of work, then went forRead More →

Last week I was invited – by the lovely Graham Lee – to talk about mobile code at the QCon London conference. I said that the most interesting thing I’d been doing in the mobile sphere was my AppInventor workshop for kids (the BCSWomen App Inventor Family Fun Day) and so I talked about that, with the title Creating Apps with 6-Year Old Girls (and their Dads) (BTW slides are available from that last link). I’ve done loads of conference speaking in the past, but the vast majority of it has been at computer vision conferences, or at women in tech gigs. Mainstream technology conferences,Read More →

This is a quick writeup of some work in progress that might never actually progress any further… so I thought I’d put it out here just in case it’s interesting to anyone. If you think of colour as computer people do, you probably think of it as red, green and blue values. In digital images, colours go from 0 to 255 in the red, green and blue channels, with 0,0,0 being black, and 255,255,255 being white. 255,0,0 is bright red. 255,255,0 is yellow. And so on. We can think of colour this way making up the colour cube: here’s a video I have put togetherRead More →

Yesterday was 5/12/13 – numbers which make up a Pythagorean triple – the sides of a right-angled triangle. A guy called Marco Matosic spotted this quirk of the date system and decided to put on an event at the Ceredigion museum, involving various people from around aber. During the day about 150 pupils from local schools came through to stroll around the exhibits and learn a bit about Pythagoras. I was there helping to run the computer installation, with Anne Marggraf-Turley from Coleg Ceredigion and Amanda Clare from aber uni (like me). Amanda and I setting up before the day began Our activity was basedRead More →

On Friday, we had a BCS Mid Wales show and tell. These are informal evening events where people who have cool projects come along and talk about them, and the BCS pays for free beer and pizza. They’re good fun, we’ve had about 5 of them now, and it doesn’t seem like we’re running out of projects. Indeed there are loads of cool things going on in and around Aberystwyth involving technology, coding, robots, and other stuff. The format of the evening is a set of short (5 minute) talks, then a break for pizza and walking around to look at stuff, then another setRead More →

This summer, Amanda Clare and I won a small grant for teaching development. The idea was to use the stuff I teach (HTML5, JavaScript) to help students learn the stuff Amanda teaches (Mathematical concepts for computer scientists). We won just under £2k from the Aberystwyth University Learning and Teaching Enhancement fund, and we spent most of it on employing Mike Sheldon, a recent Aberystywth PhD graduate. I can thoroughly recommend working with Mike – he’s not only a good coder but he’s really quick at understanding problems, and imaginative at coming up with solutions. If we manage to get funding to extend the site, I’dRead More →
