kandi X-RAY | webcv Summary

webcv is a JavaScript library typically used in Artificial Intelligence, Computer Vision, Three.js, WebGL applications. webcv has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

The getUserMedia webcam access API in modern browsers offers exciting possibilities for "runs anywhere" Computer Vision, but with the limitation that performance is typically limited by the use of JavaScript. Meanwhile, Vision algorithms are increasingly being implemented on the GPU with CUDA and OpenCL. This project takes advantage of the GPU within a browser environment by using WebGL shaders to implement a face detection algorithm in a fast, parallel way. Since WebGL is primarily a graphics API, this approach has some rough edges, and could be considered more of a stop-gap measure until projects like [WebCL] reach maturity. But the viability of Vision on the web is definitely on the rise, and with it comes the need for Vision libraries, a web-based analogue to [OpenCV] This repository has somewhat ambitiously been titled WebCV, despite only doing face detection so far. It was my [MEng project] at [Imperial] supervised by [Andrew Davison] As it grows, it would be nice to have backend-agnostic approach, giving an API that would not be tied to WebGL, and could take advantage of WebCL or other technologies if available. (Similarly to how THREE.js can fallback to a Canvas2D renderer).

QUESTION

Update in real time tooltip with react-leaflet when changing language with i18n

Asked 2020-May-01 at 09:40

I am currently displaying a Map, thanks to react-leaflet, with a GeoJSON Component. I'm also displaying some tooltips on hover over some countries and cities(for example, when I hover France, a tooltip display "France"). I'm also using i18n for internationalization. The internationalization works fine for the country tooltips, they are updated in real time.

I have a function updateDisplay, that switch between a GeoJson component for the countries, or a list of Marker for the cities, on zoom change.

The problem is, that when i'm switching languages, it works fine for the whole page, but not for the city tooltips. They are updated only when I zoom (so when the updateDisplay is called).

I would have the expected behaviour : regardless of the zoom, I would like that the city tooltips update in real time, when i switch language.

I hope I've made myself clear

Here is my code :

You can do the following to overcome this issue:

Create a boolean flag to keep in memory if the markers have been added
Add the markers on the map using native leaflet code instead of react'leaflet's wrappers.
- If the markers are added and zoom >= 4 set the flag to true
- if zoom < 4 remove the markers to be able to show countries, set flag to false
When language is changed, if zoom is bigger, equal than 4 and markers have been added remove the previous, add new ones with the new tooltip

you can achieve all these by holding a reference to the map instance.

Here is the whole code you will need, (parts of cities, markers removed):

I think the probleme is with the function onEachFeature, which is called only one time, when the JSX Element GeoJSON is created, so it does not update when we switch languages. I think so, because the tooltips are in the right language when they appears (if the language is initially set to French, the tooltips are in french, if the language is set to english, they are set to english). But they simply don't update when we change the language after the initialization of the GeoJSON component.

I hope I've made myself clear

Apparently the plugin cannot handle multiple joined strings in the form of "travel.italy.roma, travel.italy.naples, travel.italy.pompei, travel.italy.country concatenated and moreover and more importantly it seems that you need to place the function call in the markup (not 100% sure why cause I am not familiar with this plugin - maybe there is an alternative to that).

When you work with the database driver for sessions, you have to create the session table.

I'll assume you already scaffold the native authentication system by doing php artisan make:auth and migrated the migrations.

So first you generate the migration, and then migrate: php artisan session:table

Execute the migration: php artisan migrate

Obviously, this won't work if the routes you're checking on, aren't using the web middleware. If you're not registering the routes in /routes/web.php, then you have to manually specify the web middleware for them. Either in your controller's constructor, or directly in the route itself.

Edit after fix for future reference:

Also, check your domain in config/session.php is the same you're using in development or production, depending where you are working on.
