Hi Sreeni sir, I have learnt a lot from your videos and I like you to teach us the tricks like this which will be helpful for the beginners (like me). I have involved recently in cancer detection (based on images) using image segmentation (But I am from other speech-related domain) and I believe masks creation and collecting images will be challenging for the tasks. 1.Can you share any tools that will be helpful for mask creations (like Apeer) 2. Experimenting purpose datasets That will be helpful as a beginner. Thanks

Hi, awesome tutorial! Thanks. I have one question though. What if I have multiple RGB images as one input, and how should I combine / overlap them correctly to train a convolutional neural network? Ex: The shape of one image is (24,24,3). If I combine four of them, the shape would be (24,24,12)?
@sravanjosh1218

I believe it needs an additional dimension. The shape of one array with only one 3 channel image would be [1,24,24,3] and when you have four images you would have [4,24,24,3]

Thanks a lot for this video Sir. I am very new at image processing. I have a question I have, say 100 images, and the camera position is fixed. The images are of soil moving very slightly in a box. Which one of your lectures would be best to carry out analysis such that I get a video of all images where soil particles are moving. Also if I know the grid size how can I determine the amount of movement let's say in mm. Thanks and regards
@DigitalSreeni

I am not sure if I have a specific video that addresses your problem. Normally you have algorithms for object tracking where you segment objects and track them when they move. I am not sure how to do the same for soil where everything may look the same and sometime things move.

Thank you very much for your videos. I am a neuroscientist who has benefit a lot from your tutorials. I would like to respectfully make a request. I have always imagined being able to subtract the background from my microscopy images, through the patterns of a negative control image, i.e. an image that shows me all the autofluorescence and noise, but not the cells of interest. In other words, to tell the computer: "This is how a typical image without cells will look like, now, subtract that from my images containing cells". It will be possible? Thanks
@DigitalSreeni
3 жыл бұрын
You seem to be referring to subtracting a background image from another image, if so this is a simple task of just subtracting 2 images. If you are referring to background and other features as features that are not of interest compared to cells, you can train a binary classifier with your cells as objects and everything else as background.

@DigitalSreeni
3 жыл бұрын
By stacking a bunch of 2D slices (in numpy) wouldn't it effectively become a 3D image? If you are talking about using individual images of 2D projections (e.g. from x-ray) to reconstruct 3D volume then you can definitely do it. For that you need to know the theory behind FDK or iterative reconstruction. By the way, if you have segmented 2D images you can stack them to combine 2D segmented objects into 3D objects. We have a module on APEER exactly to do this task. www.apeer.com/app/modules/Measure-3D-Objects-Parameters/c0402c81-af4a-4143-88dd-fa40717df8f1
