Using YOLO on Xamarin - xamarin

I want to use object detection techniques such as YOLO in Xamarin. How can I use something like tflite or pytorch mobile on Xamarin?
If I search "C# Yolo", I can find using C# with YOLO on desktops only.

The YOLO approach has been implemented with ML.Net, which does not work in Xamarin.
Check out these articles if you want to do object detection via a service or on the device:

How do i display stuff on My Window on Windows using directx

Hello i know how to create a window using directx, but how do i display stuff on that window instead of having a totally white and blank window
Your post is missing a few key details:
What version of DirectX?
Are you using classic Win32 development or UWP?
What language? C++? C#?
If you are new to DirectX, then you should start with DirectX 11. For Win32 classic application development in C++ you can the official Microsoft Docs tutorial mentioned in the comments above. For UWP, see this page instead.
See also this blog post and Microsoft Docs.
You may also want to take a look at the DirectX Tool Kit and these VS templates.
If you are looking to render 'presentation-style' graphics rather than 3D, then you may want to take a look at Direct2D.

Here maps with Xamarin Forms

I plan to use here api to reduce my costs compared to google maps.
Is there a way to use the here map in Xamarin forms?
I have already designed the search combo suggestion to find places. Now I would like to show the places on the here map.
Thanks,
You can use android studio. The Xamarin bindings still need to be created in the SDK, as the are not on our roadmap yet.
But you can either create the bindings yourself.

map clustering in android in appcelerator titanium

I am using titanium SDK 5.0.0.GA.I have lot of map annonation on mapview.I want to load all annonation on mapview and display it as per map zoom level.I know there is one way for doing that is cluster map but I am not sure how to achieve this in android using titanium framework.
Look at Google map clustering in android
Thanks
There is a JavaScript-based library called Ti.MarkerManager to hide pins in certain zoom-levels. Unfortunately, at least iOS does not offer Clustering in their native MKMapView, yet. The Android-part could be implemented as a new feature in Ti.Map Android.

How to get Gesture events by using silverlight framework?

I try to search available option about wp7 gesture. I found only Silverlight toolkit (http://silverlight.codeplex.com/) which has gesturelistener to get gesture events. It looks like some external library to add in the application. I’m wording are there any API comes with WP7 sdk right from Microsoft. But didn’t found anything so far.
I used MouseEventHandler and MouseButtonEventHandler to get any touch event in the emulator. It is not convient for a complicated multi touch, etc.
Please give me so link to study and discover gesture API. Thanks!
The Silverlight toolkit is an external library (to the SDK) but it is produced by people working at Microsoft. Most of the developers of the toolkit also work on the SDK. It is a way for them to release more controls but on a more frequent schedule than the main SDK.
The XNA framework contains some gesture detection but this is typically more complicated to include in a Silverlight application than the toolkit.
You could also write the gesture detection yourself using the manipulation or mouse events but I'd advise against this if possible.
I'd also advise against reinventing the wheel when there are already tools available.
There are gestures built into XNA; but either way, be it Silverlight toolkit or XNA library, you would have to add a reference in your solution.
This would be a nice starting place to learn about gestures in XNA: http://www.silverlightshow.net/items/XNA-for-Silverlight-developers-Part-5-Input-touch-gestures.aspx
Hope this helps!

Is it possible to use Speech Recognition module in my application?

I saw a picture in #Matthieu's blog http://wp7wonders.wordpress.com/ yesterday(sorry,I can't find it now.
This picture have a textbox within a microphone icon just like the search page in phone.
My qusetion is can I use this feature in my application?How?
thanks.
There are no on-device or framework assemblies that you can use to perform speech recognition directly in your applications. However, Kevin Marshall has a blog post that shows how to implement speech recognition by using Web services that use System.Speech and the microphone.
