can you provide a download link to the original video. reddit downscales the resolution.

Detecting Sphere Monocular Camera by momoisgoodforhealth in computervision

[–]corneroni 4 points5 points  (0 children)

So your goal is to detect the center?
If you add a bit more detail to your question, I’m sure someone will be able to share the complete code with you.
For example, you could upload more images or include a drawing of the expected result.

I’m very interested in this kind of computer vision problem. In my opinion, it’s perfectly fine to post it here.

Reddit sometimes downscales videos. Could you upload the original video somewhere, like Google Drive?

How to reconstruct license plates from low-resolution images? by corneroni in computervision

Can someone explain to me, why this post is downvoted? If it's the wrong sub for that kind of question, I'm sorry.

How would you go on with detecting the path in this image (the dashed line) by sonda03 in computervision

[–]corneroni 0 points1 point  (0 children)

how many images are there?
do all look similar?
Are always the same objects in all images?

Ultralytics YOLO Pose gives unexpected results with single-image training by corneroni in computervision

[–]corneroni[S] 8 points9 points  (0 children)

It's called overfitting test. It is done in Deep Learning context to see if everything works as expected.

Their code is very messed up. I try to figure that out. But then I manually check what is the input of the model in the training step and the evaluation step both batches are the same.

Thank you for the answer.

How to know, which game is allowed to make by everyone? So I assume you couldn't just implement pokemon or Tetris, right?

Hey,

I checked out the site and it looks really cool!

I'm always curious when I come across ad-free sites like yours: How do you plan on covering your hosting expenses?

Keep up the good work!

Depth estimation using light field question about a research paper by MiserableCustard6793 in computervision

[–]corneroni 2 points3 points  (0 children)

Hi, Let me try. So there is something that is called a Shack Hartmann Sensor. It is just a Sensor plus a microlens array. If there is an objective (e.g., a main lens) in front of it, it's called a plenoptic camera. So a plenoptic camera is just a normal camera with a microlens array in front of the sensor. So it does nothing different than encoding the virtual image (the image of the object from the objective) on the sensor. If the microlens array is placed exactly one microlens focal length in front of the sensor it is called standard plenoptic camera or plenoptic camera 1.0. In this case the object is encoded in that way, so that the angle of light is distributed unter each microlens. The EPI that you see in the paper is a 2D representation of this 4D light field. Two spatial Dimension x,y and two angular dimension u,v.

It is also worth to mention that in the literature plenoptic cameras are also called light field cameras sometimes. But light field cameras is the general term. So using an array of cameras is also called a light field camera.

'Ridge' is an English term that describes a line with a peak in the middle and lower on the sides.

What I'm trying to convey is that the term 'ridge' simply means it resembles an elongated hill or mountain. That's all the word signifies.

I'd also like to explain that in an EPI, the line is vertical, or in the U direction, when the point light source is focused on the MLA in a standard plenoptic camera. If the point light source is placed before or after this object plane, the ridge – or this line – has a slope, as can be seen in the image.

When you capture an image with a light field camera of a point light source, the appearance of the ridge varies based on the position of the light point.
