How to tweak my code to get this smoother/fatter distance map using cv2.distanceTransform?

Asked 2022-Apr-09 at 11:49

I was reading a paper that used distance transform to get a probability map, as shown below: using the binary image: The map by the paper is so much more "concentrated and filled" (notice the fatter yellow and no pointy lines), compared to mine:

According to the paper, this is what it's described as:

...convert them to continuous distance maps by a distance transform and normalize them from 0 to 1 to form a probability map

This is my code:

Add Mouse Motion functionality to PyQt based Bezier Drawer

Asked 2022-Feb-25 at 21:05

I am trying to modify my code below to take-in mouse events (click, drag, release) such that the control points can be selected and moved, resulting in change in the curve. I am not sure where to begin, any suggestions? The control points are marked as red dots, the curve is in blue.

This would basically let me modify the curve within the gui. Any reference would be appreciated as well.

As it was suggested, for more "serious" application, You should go for GraphicsView.
Your app was however almost done with simple drawing. It's not a big deal to to modify it to work as You want.

I made few changes to Your code. You have to make list of control points as a attribute of Your BezierDrawer. Then You can use events: mousePressEvent, mouseMoveEvent and mouseReleaseEvent to interact with control points.

First we need to find out, if any point was clicked in mousePressEvent and then just update it's position while dragging. Every change of point position must end with update method, to repaint widget.

Here is modified code:

If you use HDD to store your file just reading with 100Mb/s will spend ~2min and it is a good case. Try to read a block of the file and process it in another thread while the next block will be reading.

Why FFMPEG screen recorder output shows green screen only?

Asked 2021-Dec-17 at 22:43

I am writing a screen recorder using FFMPEG lib but in output it is showing only a video with green screen. My code is below

...

ANSWER

Answered 2021-Dec-17 at 22:43

The green video is a result of encoding frames filled by zeros in YUV color space (pixel with Y,U,V value equals 0,0,0 is displayed as green colored pixel).

You are configuring sws_getContext, but you are not using it.

After decoding the grabbed video frame, the result is a frame with BGRA pixel format.
We should convert the frame from BGRA to YUV420p pixel format, and write the result to the output encoder.

When executing your code sample, I have encountered some strange behavior.
I tried to fix the code, using code snippets from the following post.

Note:

I am still learning how to use the C interface of FFmpeg.
There are implementation details that I am not sure about.
Some polishing is still required...

Goal is to generate a column pct group by id where 'pct' = (1st value of 'pts' group by 'id' * 100) / number of same consecutive 'id' value where 'x' and 'y' both are 'NaN'. For e.g. when id=1, pct = (5*100) / 2 = 250. It will loop through whole dataframe.

As has been commented, There seems to be an issue with flexdashboard in R 4.1. It does work (on MacOS) with R 3.6. I'd suggest filing an issue on their GitHub repo.

Besides downgrading R, you could also "automatically" zoom in at the beginning and use flyTo() instead of setView().

Both solutions are rather hot fixes but I am afraid that the core problem must be fixed by flexdashboard itself.
