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:

I am implementing a simple chatbot using keras and WebSockets. I now have a model that can make a prediction about the user input and send the according answer.
When I do it through command line it works fine, however when I try to send the answer through my WebSocket, the WebSocket doesn't even start anymore.
Here is my working WebSocket code:
...ANSWER
Answered 2022-Feb-16 at 19:53There is no problem with your websocket route. Could you please share how you are triggering this route? Websocket is a different protocol and I'm suspecting that you are using a HTTP client to test websocket. For example in Postman:
HTTP requests are different than websocket requests. So, you should use appropriate client to test websocket.
QUESTION
I am using MongoDB(Mongo Atlas) in my Django app. All was working fine till yesterday. But today, when I ran the server, it is showing me the following error on console
...ANSWER
Answered 2021-Oct-03 at 05:57This is because of a root CA Let’s Encrypt uses (and Mongo Atals uses Let's Encrypt) has expired on 2020-09-30 - namely the "IdentTrust DST Root CA X3" one.
The fix is to manually install in the Windows certificate store the "ISRG Root X1" and "ISRG Root X2" root certificates, and the "Let’s Encrypt R3" intermediate one - link to their official site - https://letsencrypt.org/certificates/
Copy from the comments: download the .der field from the 1st category, download, double click and follow the wizard to install it.
QUESTION
I really hope I haven't gone down a dead-end here. I have a Behaviour that gives the currently selected Color, and the current mouse coordinates, then carries out a task when the mouse is clicked. That task involves looking at a list and then updating the values in that list, for it to be retrieved later. The fact that I can "store" the selected color gives me hope that storing a list can be done in a similar manner. I'm just at a dead end and not sure how to solve this. Would really appreciate some help.
...ANSWER
Answered 2022-Jan-17 at 16:02Full credit to this response from duplode, I'll just go through how it was solved:
Let's say we have a function that modifies a list somehow, depending on some value. How/why updateMyList modifies the list doesn't really matter for this explanation, we just need to know its type. For this example, we'll say the value that determines how the list changes is a mouse coordinate tuple (x, y), which we'll pass as its first parameter:

This follows as a result of experimenting on Compiler Explorer as to ascertain the compiler's (rustc's) behaviour when it comes to the log2()/leading_zeros() and similar functions. I came across this result with seems exceedingly both bizarre and concerning:
Code:
...ANSWER
Answered 2021-Dec-26 at 01:56Old x86-64 CPUs don't support lzcnt, so rustc/llvm won't emit it by default. (They would execute it as bsr but the behavior is not identical.)
Use -C target-feature=+lzcnt to enable it. Try.
More generally, you may wish to use -C target-cpu=XXX to enable all the features of a specific CPU model. Use rustc --print target-cpus for a list.
In particular, -C target-cpu=native will generate code for the CPU that rustc itself is running on, e.g. if you will run the code on the same machine where you are compiling it.
QUESTION
I am building a Create a Recipe form using crispy forms and I am trying to use a datalist input field for users to enter their own ingredients, like 'Big Tomato' or select from GlobalIngredients already in the database like 'tomato' or 'chicken'. However, regardless of whether I enter a new ingredient or select a pre-existing one, I am getting the following error: "Select a valid choice. That choice is not one of the available choices.". How do I fix this error?
models.py
...ANSWER
Answered 2021-Dec-12 at 17:37You can create your own TextInput and TypedModelListField field to handle this. I think what you're looking for is something which allows the user to both search and provide a recommended selection of choices but validate the input against a model (Ingredient).
I've created one here:
QUESTION
I switched from the deprecated GDPR Consent Library to the new User Messaging Platform, and used the code as stated in the documentation.
I noticed that when the user clicks on Manage Options then Confirm choices, ads will stop displaying altogether (Ad failed to load, no ad config), and I can't find anyway to check if the user didn't consent to the use of personal data.
This is problematic as my app relies purely on ads, and I will be losing money if ads don't show up, so I want to make it mandatory for users to consent to the use of their personal data, otherwise the app should be unusable.
I have made a test project on Github so everyone can test this behavior. If you are not using an emulator, then you need to change the "TEST_DEVICE_ID" to yours.
How can I achieve this?
...ANSWER
Answered 2021-Nov-02 at 17:50I found a workaround for this, but this is no final official solution.
It seems that if a user consented to Personalized ads, a string in SharedPreferences, which key is IABTCF_VendorConsents, will contain ones and zeros corresponding to some vendors (I think). If he didn't consent, this string will be equal to 0.
QUESTION
The idea was to create an advanced search page that would enable users to filter data as per their choice by selecting as many as five options to narrow down their search. The results would then later get displayed on a table. Having said that, a user may decide to filter by either using only a single option i.e By state, or by taking multiple options i.e By Name, By District, and By Category or as said earlier up to 5 options. However, I have no way of figuring out how this can be done. You would find screenshots followed by the code below:
A scenario where the user chooses to filter using the By State option
Scenario, where the options are chosen are multiple to narrow down the search
The code is as follows:
...ANSWER
Answered 2021-Dec-05 at 13:35This might have a performance impact if your list is really big, but since .filter() returns back an array, why not chain 5 filters together.

Or, you can install this package from the Open UPM registry. The ToWeightedSelector method has many overloads and can be used for a variety of patterns. Since the ToWeightedSelector method is defined as an extension of IEnumerable<T>, it can be connected from the LINQ query operators. When creating a WeightedSelector, you can specify the IWeightedSelectMethod. All ToWeightedSelector methods can specify IWeightedSelectMethod. If this is not specified, the linear scan algorithm will be used automatically. The simplest algorithm that walks linearly along the weights. This method is an O(n) operation, where n is number of weights. The binary search algorithm that is faster than linear scan by preprocessing to store the current sum of weights. It has an additional storage cost of O(n), but is accelerated by up to O(log(n)) for each selection, where n is number of weights. Hiroya Aramaki is a indie game developer in Japan.
