QUESTION
I have source (src) image(s) I wish to align to a destination (dst) image using an Affine Transformation whilst retaining the full extent of both images during alignment (even the non-overlapping areas).
I am already able to calculate the Affine Transformation rotation and offset matrix, which I feed to scipy.ndimage.interpolate.affine_transform to recover the dst-aligned src image.
The problem is that, when the images are not fuly overlapping, the resultant image is cropped to only the common footprint of the two images. What I need is the full extent of both images, placed on the same pixel coordinate system. This question is almost a duplicate of this one - and the excellent answer and repository there provides this functionality for OpenCV transformations. I unfortunately need this for scipy's implementation.
Much too late, after repeatedly hitting a brick wall trying to translate the above question's answer to scipy, I came across this issue and subsequently followed to this question. The latter question did give some insight into the wonderful world of scipy's affine transformation, but I have as yet been unable to crack my particular needs.
The transformations from src to dst can have translations and rotation. I can get translations only working (an example is shown below) and I can get rotations only working (largely hacking around the below and taking inspiration from the use of the reshape argument in scipy.ndimage.interpolation.rotate). However, I am getting thoroughly lost combining the two. I have tried to calculate what should be the correct offset (see this question's answers again), but I can't get it working in all scenarios.
Translation-only working example of padded affine transformation, which follows largely this repo, explained in this answer:

When I read data from GPS sensor, it comes with a slight delay. You are not getting values like 0,1 0,2 0,3 0,4 0,5 etc, but they are coming like 1 then suddenly 5 or 9 or 12. In this case needle is jumping back and forth. Anybody have an idea how to make needle moving smoothly? I guess some kind of delay is needed?

Answered 2022-Mar-21 at 22:09Coming from a controls background, to mimic behavior of an analog device, you could use an exponential (aka low-pass) filter.
There are two types of low-pass filters you can use, depending on what type of behavior you want to see: a first-order or second-order filter. To put it in a nutshell, if your reading was steady at 0 then suddenly changed to 10 and held steady at 10 (a step change), the first order would slowly go to 10, never passing it, then remain at 10 whereas the second order would speed up its progress towards 10, pass it, then oscillate in towards 10.
The function for an exponential filter is simple:

QUESTION
I am trying to solve a problem without success and am hoping someone could help.
I have looked for similar posts but haven't been able to find anything which solves my problem.
My Scenario is as follows:
I have a UIView on which a number of other UIViews can be placed. These can be moved, scaled and rotated using gesture recognisers (There is no issue here).
The User is able to change the Aspect Ratio of the Main View (the Canvas) and my problem is trying to scale the content of the Canvas to fit into the new destination size.
There are a number of posts with a similar theme e.g:
calculate new size and location on a CGRect
How to create an image of specific size from UIView
But these don't address the changing of ratios multiple times.
My Approach:
When I change the aspect ratio of the canvas, I make use of AVFoundation to calculate an aspect fitted rectangle which the subviews of the canvas should fit:
ANSWER
Answered 2022-Feb-06 at 10:03Here are a few thoughts and findings while playing around with this
1. Is the right scale factor being used?
The scaling you use is a bit custom and cannot be compared directly to the examples which has just 1 scale factor like 2 or 3. However, your scale factor has 2 dimensions but I see you compensate for this to get the minimum of the width and height scaling:
QUESTION
I've built this new ggplot2 geom layer I'm calling geom_triangles (see https://github.com/ctesta01/ggtriangles/) that plots isosceles triangles given aesthetics including x, y, z where z is the height of the triangle and
the base of the isosceles triangle has midpoint (x,y) on the graph.
What I want is for the geom_triangles() layer to automatically provide legend components for the height and width of the triangles, but I am not sure how to do that.
I understand based on this reference that I may need to adjust the draw_key argument in the ggproto StatTriangles object, but I'm not sure how I would do that and can't seem to find examples online of how to do it. I've been looking at the source code in ggplot2 for the draw_key functions, but I'm not sure how I would introduce multiple legend components (one for each of height and width) in a single draw_key argument in the StatTriangles ggproto.
ANSWER
Answered 2022-Jan-30 at 18:08I think you might be slightly overcomplicating things. Ideally, you'd just want a single key drawing method for the whole layer. However, because you're using a Stat to do the majority of calculations, this becomes hairy to implement. In my answer, I'm avoiding this.
Let's say I'd want to use a geom-only implementation of such a layer. I can make the following (simplified) class/constructor pair. Below, I haven't bothered width_scale or height_scale parameters, just for simplicity.
QUESTION
So I am just a beginner and I am just trying to figure out animations and how they work.
My plan is to move the ball infinitenly in an infinite number of degrees (lets say 90) on a line. Here are a couple of problems I wondered:
- Is there a better way to use classes that have common and slightly different rules (having different rotations) ?
- How can I have the ball movement on the new lines having different rotations?

I'm trying to detect angle difference between two circular objects, which be shown as 2 image below.
I'm thinking about rotate one of image with some small angle. Every time one image rotated, SSIM between rotated image and the another image will be calculated. The angle with maximum SSIM will be the angle difference.
But, finding the extremes is never an easy problem. So my question is: Are there another algorithms (opencv) can be used is this case?

Thanks @Micka, I just do the same way he suggest and remove black region like @Yves Daoust said to improve processing time. Here is my final result:

- detect circles (for the example I assume circle is in the image center and radius is 50% of the image width)
- unroll circle images by polar coordinates
- make sure that the second image is fully visible in the first image, without a "circle end overflow"
- simple template matching

QUESTION
Thanks for taking the time to review my post. I hope that this post will not only yield results for myself but perhaps helps others too!
IntroductionCurrently I am working on a project involving pointclouds generated with photogrammetry. It consists of photos combined with laser scans. The software used in making the pointcloud is Reality Capture. Besides the pointcloud export one can export "Internal/External camera parameters" providing the ability of retrieving photos that are used to make up a certain 3D point in the pointcloud. Reality Capture isn't that well documented online and I have also posted in their forum regarding camera variables, perhaps it can be of use in solving the issue at hand?
Only a few variables listed in the camera parameters file are relevant (for now) in referencing camera positioning such as filename, x,y,alt for location, heading, pitch and roll as its rotation.
Currently the generated pointcloud is loaded into the browser compatible THREE.JS viewer after which the camera parameters .csv file is loaded and for each known photo a 'PerspectiveCamera' is spawned with a green cube. An example is shown below:
The challengeAs a matter of fact you might already know what the issue might be based on the previous image (or the title of this post of course ;P) Just in case you might not have spotted it, the direction of the cameras is all wrong. Let me visualize it for you with shabby self-drawn vectors that rudimentary show in what direction it should be facing (Marked in red) and how it is currently vectored (green).
Row 37, DJI_0176.jpg is the most right camera with a red reference line row 38 is 177 etc. The last picture (Row 48 is DJI_189.jpg) and corresponds with the most left image of the clustured images (as I didn't draw the other two camera references within the image above I did not include the others).
When you copy the data below into an Excel sheet it should display correctly ^^
...ANSWER
Answered 2022-Jan-02 at 22:26At first glance, I see three possibilities:
It's hard to see where the issue is without showing how you're using the
createCamera()method. You could be swappingpitchwithheadingor something like that. In Three.js, heading is rotation around the Y-axis, pitch around X-axis, and roll around Z-axis.Secondly, do you know in what order the
heading, pitch, rollmeasurements were taken by your sensor? That will affect the way in which you initiate yourTHREE.Euler(xRad, yRad, zRad, 'XYZ'), since the order in which to apply rotations could also be'YZX', 'ZXY', 'XZY', 'YXZ' or 'ZYX'.Finally, you have to think "What does
heading: 0mean to the sensor?" It could mean different things between real-world and Three.js coordinate system. A camera with no rotation in Three.js is looking straight down towards-Zaxis, but your sensor might have it pointing towards+Z, or+X, etc.
I added a demo below, I think this is what you needed from the screenshots. Notice I multiplied pitch * -1 so the cameras "Look down", and added +180 to the heading so they're pointing in the right... heading.

What happens:
...ANSWER
Answered 2021-Dec-18 at 21:12To avoid overflowing, you can use the rule white-space: nowrap; for your h1.
However, that will avoid breaking the line after "Hello," as well.
So I would also recommend adding a Hello, for explicitly breaking that line.
That should solve your line-break issues, but I noticed you're also rotating the text by 90deg, and that can mess up the heading fitting inside the cell.
So I recommend adding the rule writing-mode: tb-rl (link) to make the text be written vertically, and then rotating it 180deg instead of 90 (so it becomes bottom-up instead of top-down)
