ANSWER
Answered 2021-Jun-11 at 09:42Does n_classes signify multiclass segmentation?
Yes, if you specify n_classes=4 it will output a (batch, 4, width, height) shaped tensor, where each pixel can be segmented as one of 4 classes. Also one should use torch.nn.CrossEntropyLoss for training.
If so, what is the output of binary UNet segmentation?
If you want to use binary segmentation you'd specify n_classes=1 (either 0 for black or 1 for white) and use torch.nn.BCEWithLogitsLoss
I am trying to use this code for image denoising and I couldn't figure out what will should the n_classes parameter be
It should be equal to n_channels, usually 3 for RGB or 1 for grayscale. If you want to teach this model to denoise an image you should:
- Add some noise to the image (e.g. using
torchvision.transforms) - Use
sigmoidactivation at the end as the pixels will have value between0and1(unless normalized) - Use
torch.nn.MSELossfor training
Because [0,255] pixel range is represented as [0, 1] pixel value (without normalization at least). sigmoid does exactly that - squashes value into [0, 1] range, hence linear outputs (logits) can have a range from -inf to +inf.
Why not a linear output and a clamp?
In order for the Linear layer to be in [0, 1] range after clamp possible output values from Linear would have to be greater than 0 (logits range to fit the target: [0, +inf])
Why not a linear output without a clamp?
Logits outputted would have to be within [0, 1] range
Why not some other method?
You could do that, but the idea of sigmoid is:
- help neural network (any logit value can be outputted)
- first derivative of
sigmoidis gaussian standard normal, hence it models the probability of many real-life occurring phenomena (see also here for more)
QUESTION
I have the below script attached to my main camera. Its for a VR app. The script allows me to rotate the camera when pressing down on the mouse button.
The script works but the problem is, while I have the mouse button pressed down the view slightly keeps rotating towards the left. When I release the mouse button the movement stops.
I cant find the cause of this "ghost" movement

QUESTION
The red circle is at a known angle of 130°, then I want to draw the navy line from the center to 130° using x and y of the red circle but it looks like I missed the calculation.
Currently, the angle of the Navy line is a reflection to the angle of the red line and if I add minus sign ➖ to *diffX * at line13, it'll work as expected but Why do I need to do that by myself, why can't the Calculations at line 10 and 13 figured out if x should be minus ➖ or plus.
I couldn't figure out where I was wrong..any help/suggestions are appreciated!
...ANSWER
Answered 2021-Feb-21 at 16:07Seems you are using too much minuses.
At first, you define angle -130 degrees, close to -3Pi/4. Cosine and sine values for this angle are about -0.7, using hypothenus = 100, we get x =W/2-70, y = H/2-70

ANSWER
Answered 2020-Nov-23 at 22:36As you say the code seems to work - I copied into the snippet below which you can run here. I added some console logging to see what was going on. The only change I made was to the width & height vars which were both set at 800 when in fact the image is 400 x 400. Maybe that was your issue. Otherwise it appears to work.
You might want to consider breaking the image into a grid of squares, say 20x20px. Then maybe mark where the player clicked already with a semi-transparent div.
QUESTION
In my libgdx test game, I have initially created 2 circle objects (stellar) about which I will say more in details below. However, my goal is to simulate gravity in 2d, where smaller object orbits towards center of bigger object (just like earth orbits sun) but closer and closer to the center of bigger.
So, I have created the following:
- stellar1: smaller, 10px radius, 10 mass, dynamic (can move), initial position -160x90, velocity (0,0), accelerator (0,0)
- stellar2: bigger, 30px radius, 30 mass, static (cannot move), initial position 0x0, velocity (0,0), accelerator (0,0)
Here is also a screenshot, just to have a picture:
I will give the full code below of what I did so far, before that I want to mention I have 2 approaches, StellarTest1 and StellarTest2.
First StellarTest1, I've tried to add some extra values like 1000f to both x and y just to see something in action like:
...ANSWER
Answered 2020-Nov-22 at 16:47Your update approach in StellarTest1 looks conceptually fine to me (I assume this 1000f factor is way to adjust the gravitational constant/mass of the bigger body). However, of you want some extra decay of the orbit, you need to add some fictitious velocity-dependent drag term to the acceleration. There is no need of StellarTest2, because you should get a comparable results while the calculation of cos and sin is slower and expensive, while the same components in StellarTest1 are calculated in a purely algebraic way (multiplication and division) which are much faster.
But to achieve some interesting orbit you need not only the two coordinates of the initial position of the smaller object, but also the two coordinates of the initial velocity of the smaller object! Without specifying the initial velocity or assuming it is zero you are not going to get a nice curved orbit. You need to choose initial velocity. Also, the orbits should not get nowhere near the center of the big object, because the Newtonian gravitational force-field has a singularity at the center of the bigger body, so the closer the smaller body gets to that singularity, the worse the orbit will look (and the numerical errors will blow out of proportion) and it is not surprising you are getting the smaller body shot out of the center of the bigger one.
In general there is a way to choose a velocity that will send the smaller body on an elliptic orbit with predefined orbital parameters: the length of the semi-major axis a, orbital eccentricity e, the angle omega between the semi-major axis and the horizontal x-axis and the angle f (called true anomaly) between the position vector from the bigger to the smaller body and the the semi-major axis.
QUESTION
Sorry if this has been asked before i did search and couldn't find anything.
I am currently in the process of creating a react application and need to render details to a canvas. The program itself is going to be a map creation program. Currently I'm drawing to the canvas with the canvas context, although I want to change this out to konva or ocanvas eventually.
My isssue at the moment is I'm struggling to find a nice way to seperate everything as the canvas need to handle lots of mouse events, rendering the data, and "tool" selection and some data manupulation. Ideally I'd like to seperate this code out to a seperate units so all of the code isn't in one place. IE: rendering logic, input logic, etc... How would I go about doing this? bearing in mind the map MAY need to be passed into the sub unit.
Below is a snippet of the code i currently have i have removed some of the granular details but have kept all my mouse code and values:
...ANSWER
Answered 2020-Nov-11 at 12:51After some considerations and thinking about the problem i have come up with the following solution:
Within the canvas class create and initlise a list of "tools" part of this inilisation is giving a list of callback functions to update the state IE: render scale & offsets. the within the event functions for the canvas call the event within the selected tool.
This method is quite expandable as any functions can be added to the callback, this means the tools can be coded to do anything. I also added a render function to the tool which get's called last and can render custom elements to the screen depending on the tool.
