should I have sub-folders for each year? each month? etc.

How granular I should be with sub-folders.

In my case, the only way I can think of that I'd treat them differently is in the event that I wanted to replicate just the pictures or just the videos, and possibly if I wanted a different snapshot schedule as I backup more pictures, more often than I do videos.

Should I have nested Pictures and Videos Datasets? I've always read that Datasets should be used when you want to treat the data within it differently to other data.

What do I do in the event that a files original creation date is not available?.

Here are the questions I've been asking myself. There are a few things I haven't made my mind up on though. I also be renaming everything so that all the files start with the date they were created (YYYY-MM-DD_HH.MM.SS), so that I can sort everything chronologically.

There's some unrelated weirdness with the current Dataset that means that I'll be creating a new Dataset and moving files to it as I sort them. There is two things I'm set on though, first being that I' ll be creating a new Dataset.

I'm finally gonna tackle the jumbled, duplicate filled mess that is my Pictures_and_Videos Dataset but I'm undecided on how to do it. Did you try to run your program separately? I think it will work fine.I'd very much like to hear who all of you organise your family pictures and videos, and how you and your family view them? As this issue is still present, I am wondering if the bottleneck is in the USB communication or multiple threads for video capture might overload the processor (I doubt the latter is the case).

In the case of Mac Book Pro, I could capture the images from at most 2 cameras, whereas in the case of Ubuntu Desktop, I could capture only images from a single camera.

>I tried to connect 4 USB cameras through an externally powered USB hub and run the script on two different computers, Mac Book Pro and Ubuntu machine with core i7 processor and 32 GB RAM.

A good motherboard with high-end chipset for better link speed.

Sometimes the USB hub won't give camera enough power or bandwidth

Connect each camera directly to the USB board without using USB hub.

Most of the problems came from how to keep all of the camera stables. I did the similar thing before using 6 realsense camera. Might also need to do some interpolation as it's likely you'll get some misses due to motion blur, etc.

Speaking of tracking my guess is you'd probably need to implement some logic on top to record where you've seen a given code based on your detections from ZBar. Since you're tracking, you could maybe make informed choices of where to look with ZBar based on the motion of the camera/object, either with optical flow directly or using a kalman filtering type approach based on previous directions. I used the gradients of the image to detect qr-type regions to subsequently test with ZBar: the nature of qr codes means they show pretty well as high frequency gradient regions. If the qr code is relatively small, it might be worth doing some image processing in advance to make its life easier.

It's rotation (and largely, scale) invariant, handles detection and decoding and is free and open source. I used it previously and it does a pretty awesome job of qr detection, provided the code takes up enough of the image. If you just need it done, rather than doing it as a learning exercise, I'd recommend ZBar ( ). If you're doing it to learn computer vision techniques, the recommended tutorial from hwillis is great. But then again, maybe the company have enough knowledge on image processing, and are looking for people with other types of knowledge, such as parallel programming, to help them scale/speed-up their existing processes. For companies that are looking for candidates with image processing skills, people with more experience in image processing will probably be taken more seriously than those with no experience.

See what kind of posting/industry that interest you most, and see what kind of skills (programming language, libraries, particular knowledge) they are seeking. To know what the job market is like, you can search on using image processing related keywords like: 'Image processing', c++, cuda, 'open cv', 'machine learning' + your existing skill set. That being said, you probably should work on some projects related to image processing to first understand and learn what is image processing, and if it is indeed interesting to you. With a physics background, the basic image processing operations/concepts probably will be fairly easy for you to grasp. 'I thought image processing could be interesting'
