I have a csv file that contains some columns. The columns of interest have multiple json objects in a single row. it looks something like this:

Currently, I'm working on image stitching of aerial footage. I'm using the dataset, get from OrchardDataset. First of all, thanks to some great answers on stackoverflow, especially the answer from @alkasm (Here and Here). But I having an issue, as you can see below at Gap within the stitched image section.

I used the H21, H31, H41, etc to wrap the images. The stitched image using H21 is excellent, but when wrap the img3 to current stitched image using H31, result shown terrible alignment between img3 and current stitched image. As the more images I wrap, the gap gets bigger and the images totally not well aligned.

Does the brillant stackoverflow community have an ideas on how can I solve this problem?

These are the steps I use to stitch the images:

1. Extract the frame every second from the footage and undistort the image to get rid of fish-eye effect using the provided camera calibration matrix.
2. Compute the SIFT feature descriptors. Set up macther using FLANN kd-tree and find matches between the images. Find the Homography (H21, H32, H43 and etc, where H21 refer to the homography which warps imag2 into coordinates of img1)
3. Compose the homography with the previous homographies to get net homography using the method suggested in Here. (Compute H31, H41, H51, etc)
4. Wrap the images using the answer provided in Here.

Gap within the stitched image:

I'm using the first 10 images get from OrchardDataSet.

Stitched Image with Gaps

Here's portion of my script:

main.py

ref_img is the first frame (img1). AdjHomoSet contain the images to be wraped (img2, img3, img4, etc). AccHomoSet contain the net homography (H31, H41, H51, etc)

I have a table with CLOB column storing a XML. The structure of XML is unreadable. I want to get values between few tags like ; sample is shown below.

I have a multi-module maven project, and trying to use Jacoco to generate an aggregated report, and run 'aggregated' checks. However, I cannot in any possible way get the Jacoco merge function to work through the maven plugin. Therefore I tried to create a minimal example, as illustrated below

The project only contains three files, the maven pom file, and two Jacoco exec files (previously generated)

• Root folder
  • pom.xml
  • jacoco1.exec
  • jacoco2.exec

The pom file content looks like the following:

I'm checking in DB if there is a matching date. If there is a match, it gets send back. I do this with a GET request.

In my .ts class I then want to look if the returned value is empty or not.

I'm currently implementing two apps: a client app which communicates with another server app via TLS Socket connection. The server phone (Android 7.1) needs to create a hotspot with passphrase (can be set up in the Android hotspot settings). This connection works fine, if I connect the client phone (Android 10) to the hotspot via the "Android System Wi-Fi Panel" (tap on Wi-Fi, select hotspot, enter passphrase → connected). My Socket connection can be established - client and server can communicate.

The client phone reports, that there is no internet available within this hotspot, which is ok since I don't want to access its internet connection.

But now, I want to connect directly to it via the WifiManager and a self created WifiConfiguration by using the following code, without going to the Android settings:

I am struggling to get this regex going. Here is the string I am trying to work with.

I have a csv file of 100000 ids

I'm new to C# and can't seem to figure this one out.

In my application I have a code preprocessing module that allows me to manipulate a file (in this case a csv file) before loading it into my application for processing it into my database. One of the files that comes to my application has a column named "Business ID" that I need removed before I move forward in the rest of my preprocessing. There are various files this same code is used to read in and the only difference between them is that this one CSV file has that extra "Business ID" field. It will only need to be removed if the column is present.

Before someone recommends it, the column cannot be removed outside of the program or during the csv generation - it has to be done in this preprocessing.

My code is below - I redacted information in some of the case statements for confidentiality but the remainder of the code is in tact. I appreciate any help y'all can give!

EDIT: Per request here's as much of a snippet as I can provide of the .csv file. This is just the headers. I can't provide an actual record. Hope this is enough for what you wanted to see.
