kandi X-RAY | contracting Summary

contracting is a Python library typically used in Financial Services, Fintech, Blockchain, Ethereum applications. contracting has no bugs, it has no vulnerabilities, it has build file available and it has low support. However contracting has a Non-SPDX License. You can install using 'pip install contracting' or download it from GitHub, PyPI.

Contracting is the name of Lamden's smart contracting library. Unlike Bitcoin and Ethereum, Lamden leverages the existing PythonVM to create a system that allows developers to write small applications for the types of logic we see in smart contracts today. This generally has to do with simple logical transactions. Contracting focuses on making standard CRUD operations extremely easy with full support for JSON objects and dynamic storage sizing so you spend less time with lower level computer science details and more time coding.

trying to resolve missing file for dll .net app

Asked 2022-Feb-05 at 18:28

I inherited a .NET app using ArcGIS with next to know documentation and I'm just trying to get it up an running locally right now and I'm encountering some difficulties. I'm missing references to a few DLL's and was hoping someone could tell me which SDK(s) I needed to install to find them. I already have the standard .NET SDK v100.13 and I have the local server SDK v100.12 Here is a list of this missing DLL's that are being used:

ESRI.ArcGIS.Framework

ESRI.ArcGIS.ADF (I know this one has been separated into ADF.Local and another binary)

ESRI.ArcGIS.Catalog

ESRI.ArcGIS.Controls

ESRI.ArcGIS.BaseClasses

ESRI.ArcGIS.ArcMapUI

This app was made, I believe, in 2014 by a third party contracting company which no longer exists so I can't really reach out to them for any support. Are these DLL's from a deprecated SDK? Any help would be appreciated and if you need further information I will try my best to diligently respond, edit, and update my questions based on feedback.

Looks like ArcObjects. Typically it is used to build customizations in ArcGIS Desktop (ArcMap, ArcCatalog). ArcObjects is also used with ArcGIS Engine to build stand-alone apps that include ArcGIS components. If it's an ArcGIS Desktop customization (e.g., add-in), then you would need to install ArcGIS Desktop, along with the ArcObjects SDK. If it's a stand-alone app, then the ArcGIS Engine Developer Kit. ArcObjects is not deprecated yet.

QUESTION

When will camera distortion coefficients change

Asked 2021-Dec-08 at 03:06

If I capture a single view of a checkerboard pattern with known real world coordinates I can use ,for example, the OpenCV calibrateCamera function to calculate the distortion coefficients of that camera.

These distortion coefficients are intrinsic parameters, not dependent on camera pose, so if the camera moves the distortion coefficients do not change, at least that is my understanding. My question is when would these coefficients change? I believe they can change with changes in temperature with components in the system (pixels, lens, mounts, etc..) expanding and contracting, but temperature can potentially be controlled.

Can the distortion be calculated once for a system and never again? What if a lens is removed and then reinstalled? What if the distance to the objects being imaged changes (working distance)?

I haven't been able to find much discussion of this anywhere.

...

ANSWER

Answered 2021-Dec-08 at 03:06

You have to define the term "change" first. E.g would you consider +0.0001 in your distortion parameter as a change? Whatever you do the intrinsic and the lens distortion parameters always change at least a small bit.

Those are the cases I usually do the recalibration where the application is a high-end industrial-grade measuring device:

when the lens locking screw was touched.
when the lens focus was adjusted.
when the working environment has changed. (humidity, temperature)
when I dropped the device.
when somebody touched the lens part.

If your application is not very sensitive to accuracy, just do the recalibration when the lens is replaced or focus is adjusted.

How to automatically delete a matrix column in R if there otherwise would be subscript out of bounds error?

Asked 2021-Oct-17 at 08:32

The below images show what happens when running the below MWE code and what I'm trying to solve for:

The first image shows the user having input two additional interpolation scenarios, in addition to default "Scenario 1". Note how the cursor remains under Scenario 3, as the user prepares to delete Scenario 2.
The second image shows the error that results after the user deletes the Scenario 2 from the first image by having clicked on the [x] in the Scenario 2 column header, while the cursor was still under Scenario 3. (Note that this error WOULD NOT have occurred had the cursor been placed under Scenario 2 -- but I'm trying to account for real-world user inputs).
The third image shows the result of the user correcting for the error by clicking on the [x] deletion symbol in the extraneous, empty Scenario 3 in the second image.

It's natural in an expanding/contracting matrix like this that there would be subscript out of bounds errors.

My question is: how can I automate the deletion of the last column when there would otherwise be a subscript out of bounds error?

ANSWER

Answered 2021-Oct-17 at 08:32

I made quite a few changes so let me just highlight the most important ones:

The crucial change probably was this: I re-inserted the code to remove empty cells from the matrix in observeEvent(input$myMatrixInput. The code had originally been provided by the PO but removed in search for a solution. I added drop=FALSE in the sub-setting statement tmpMatrix <- tmpMatrix[, !empty_columns, drop=FALSE] to make it work because we need to preserve the matrix type. If you do not do this, the code will break.
sanitizedMat removed. Everything can be done with the matrix input and it did not bring any value. On the contrary, it made it more complex, more difficult to understand ... and complex also always means more error-prone.
Added an isolate around updateMatrixInput to avoid dependencies.
Added a tryCatch in the plotData reactive because matrixInput temporarily sent values that could not be interpreted. Now the reactive returns NULL when matrixInput is not valid and renderPlot won't be run because of the req(plotData()).

ANSWER

Answered 2021-Sep-06 at 15:17

Your problem is that the images does not have a dimension as a power of 2, for example having a dimension like 256 or 512 will not create this problem, this happens because in your network you have pooling layers that generate images of half the size, and when you divide more times 300 for 2 you get the series: 150 and 75 and 75 is not divisible for 2, so when you try to divide 75 you get size 37 and when you do the traspose of the level beneath you get size 36.

i don't know if it was clear enough: you are trying to do the maxpooling of an image with an odd number of pixel, the image will go 300 -> 150 -> 75 -> 37 -> 18 and the get dubled 18 -> 36 STOP, 36 and 37 are not equal and the network can't concatenate

So, fast solution: resize the images to have a dimension as a power of 2, like 512, or at the very least a size divisible for 8 ( because you have 4 maxpooling)
