blobs | mirror of the blobs repository

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 trying to speed up the querying of some json data stored inside a PostgreSQL database. I inherited an application that queries a PostgreSQL table called data with a field called value where value is blob of json of type jsonb.

It is about 300 rows but takes 12 seconds to select this data from the 5 json elements. The json blobs are a bit large but the data I need is all in the top level of the json nesting if that helps.

I tried adding an index of CREATE INDEX idx_tbl_data ON data USING gin (value); but that didn't help. Is there a different index I should be using? The long term vision is to re-write the application to move that data out of the json but that is something is at least 30-40 man days of work due to complexity in other parts of the application so I am looking to see if I can make this faster in short term.

Not sure if it helps but the underlying data that makes up this result set doesn't change often. It's the data that is further down in the json blob that often changes.

I have a Public Sub to move a collection of records from one table to another in the same SQLite database. First it reads a record from strFromTable, then writes it to strToTable, then deletes the record from strFromTable. To speed things up, I've loaded the entire collection of records into a transaction. When the list involves moving a lot of image blobs, the db gets backed up, and throws the exception "The Database is Locked". I think what is happening is that it's not finished writing one record before it starts trying to write the next record. Since SQLite only allows one write at a time, it thows the "Locked" exception.

Here is the code that triggers the error when moving a lot of image blobs:

What is the VB.net equivalent to await foreach found in C#?

Based on what i have found VB.net's For Each cannot use the Await operator (Await Operator (Visual Basic))

For example how would this C# example be converted to VB.net (List blobs with Azure Storage client libraries)?

In my Java application I am using Azure Data Lake Storage Gen2 for storage (ABFS). In the class that handles the requests to the filesystem, I get a file path as an input and then use some regex to extract Azure connection info from it.

The Azure Data Lake Storage Gen2 URI is in the following format:

let's say I have blob structure like this:

dir0
├── dir1
│ ├── file11
│ └── file12
├── dir2
└── dir3

After listing the dir1 that contains two files file11, file12 with listBlobsByHierarchy("dir0/dir1/") method I'm getting two blobs with blobName property set to dir0/dir1/file11 and dir0/dir1/file12, so /. That's OK, but in some point I need to get the part.

My question is: Does Azure Storage SDK 12 for Java provides a mechanism for obtaining part from blob name? I could do it myself but it's hard to believe that SDK doesn't provide this functionality... Maybe you guys know different elegant way to do so? How do you usually handle such things?

It's a bit weird to me that SDK seems not to support building prefixes or getting file names from blob names :P I expected sth like fileName field in BlobItem class or buildPrefix(List segments) method for joining path segments with '/'.

I have one old Azure Functions project (v3). It contains several timer triggered functions. They stopped working on VS2022. You can see the logs below. If I create a new Functions project via VS2022, it will work fine. Looks like Azurite also starts up fine. Setting "AzureWebJobsStorage" equals "UseDevelopmentStorage=true". What can I do?

I have some blobs that are animated as a background for my webpage but the problem is that they are overflowing on the page causing my content to not be responsive. I have tried adding position: relative and position: absolute as well as overflow:hidden but nothing seems to work. Here is the code I have and I appreciate any help I can receive!

I was trying to build a new image for a small dotnet core 3.1 console application. I got an error:

I have checked an old dotnet program which my dockerfile was working perfectly. I got the same error. Then, I jumped to Docker Hub and checked the MS Images to see that all MS images have been updated for an hour. And then they have been updated once again, 10 Minutes ago xD. However, I still cannot pull the base images of mcr.microsoft.com/dotnet/runtime:3.1 and mcr.microsoft.com/dotnet/sdk:3.1. My whole Dockerfile is:
