QUESTION
I am trying to find the locations of objects across 3 overlayed images. Essentially I take an image in 3 different spectrums and overlay them for data extraction of concentrations. I run a circle analysis on it and then compare each item to see if it is close enough to be overlapping. The below algorithm is working but the number of comparisons makes this algorithm run for around 2 mins each time and I need it to be something like 1-5 seconds each time as I have to do hundreds of the comparisons in the final product.
I am midway in trying more complex algorithms but thought I would ask since there may be a much simpler way and I am overthinking it.
My lists are on average 100-500 items long.
"Better" algorithms:
divide the images into multiple overlapping sectors and doing the same comparison in each region then filtering out the overlap. I have done something similar before but the final filter was exceedingly complicated.
Sort all 3 lists into a single list that is "diagonally" sorted and comparing each item to one or two away from its location. Currently, my sorting algorithm is to slow to be useful and I can't fix the "localization" problem.
(Currently the forerunner) I am taking the 3 images mixing them into one, overlaying my previous detection algorithm, taking the average color of the feature, and then running a clustering algorithm to separate it.

Answered 2020-Jul-20 at 22:14In essence your program compares three lists of numbers by iterating over each combination. If the lists have n elements, you are doing n3 comparisons. This is highly inefficient. You could instead map the green to the gray, and then the blue to the gray, leading to only 2n2 comparisons. Still, it is not necessary to do this looping, since images provide a spatial indexing for you. You can find the location of each circle in the gray image, then look at those locations in the green and blue images to see if those pixels are bright enough to consider them "on".
This is made slightly difficult by the slightly overlapping circles, and by the slight displacement between the images. It might be necessary to do an image registration first if the displacement gets worse than in this example.
This is how I would implement it using DIPlib:

...ANSWER
Answered 2020-Feb-25 at 11:12Sendmail requires 3 arguments to be passed to it. A from address, a list of to addresses, and a message thats to be sent.
from the documentation https://docs.python.org/3/library/smtplib.html#smtplib.SMTP.sendmail
The required arguments are an RFC 822 from-address string, a list of RFC 822 to-address strings (a bare string will be treated as a list with 1 address), and a message string.
You need to update your code where you call server.sendmail to include a from address and a to address and then your msg.

Context: I have a file that contains several hundred lines of JSON.The T-SQL below is able to convert a single line of the JSON file into tabular form.

...ANSWER
Answered 2019-May-30 at 20:26The way you're using 'term' in your for loop makes 'term' a string (one of ['spartan', 'forerunner', 'didact']). You're looking for an integer to use in "result[term]", so, stick with enumerate, but remember using enumerate the first part of the tuple is the "enumeration" and the second part is the item.

QUESTION
I am running a project with ASP.NET Core (2.1) MVC. In our company we do have a lot of work done with SQL Report Builder (rdlc and rdl files). Therefore we wanted to use a "one the fly" mechanism to generate PDF Files with the ReportBuilder technology in the asp.net core mvc webapp.
I tried the same nuget packages we are using in .net Framework (asp.net API and desktop app) but they are not working. The packages I tried are:
- Microsoft.ReportingServices.ReportViewerControl.Winforms
- Microsoft.ReportingServices.ReportViewerControl.Webforms
The problem there is that they are using System.Web which I cannot include in .net Core apps, do I?
I googled for any solution but did not find a lot of helpfull material. I am also ware of that Microsoft purchased a product to get the work done: https://blogs.msdn.microsoft.com/sqlrsteamblog/2018/04/02/microsoft-acquires-report-rendering-technology-from-forerunner-software/
And I already read this article about a similar problem: RDLC Local report viewer for ASP.NET Core and Angular(>2.0)
Do we have the wrong technology setup in mind or is this even not support at all. I found some other package (https://www.nuget.org/packages/AlanJuden.MvcReportViewer.NetCore/) which are working with html to render a report. But we really want to use the rdl files
Any informations and suggestions are greatly appreciated.
...ANSWER
Answered 2019-Feb-22 at 13:33In the end we came up with a totally other approach.
We just created a new Application called "DocumentService" on .NET Framework running as a Service on a Windows Server. The service was checking a database if there are new jobs in the database queue and if so, it generates the pdf result and stores it in the database.
So the web application was not longer responsible for creating the pdf, it only added a new line in the database so mark that a new document should be created. The DocumentService app then generated the document and the web app could access the data in the database.
We can use this "DocumentService" in other part of our application landscape and therefore the effor was worth it. It app is also multithreaded and working pretty fast and well.

QUESTION
Given the following XML document.
...ANSWER
Answered 2017-Jan-16 at 23:35There are two reasons why your current attempt doesn't work:
The default namespace used by your input XML is
"http://www.garmin.com/xmlschemas/TrainingCenterDatabase/v2", not"http://www.garmin.com/xmlschemas/TrainingCenterDatabasev2.xsd"as you're declaring in your stylesheet;The path to the
Trackelement is incorrect - you've missed theLapstep.
Fixing these two will get you a result that is a deep copy of the Track element.
However, I doubt that is the result you want, since it will be copied as is - including the default namespace. In order to get a result that is in no-namespace, you need to create new elements instead of copying from the source. Try, for example:
