B4A Library Onyx

DonManfred · Aug 14, 2016

this is a wrap for this Github Project.

An android library that uses technologies like artificial Intelligence, machine learning, and deep learning to make developers understand the content that they are displaying in their app.

Please note that this lib used service from Clarifai which is not totally free (https://clarifai.com/pricing)

Onyx
Author: DonManfred (wrapper)
Version: 1

OnyxTags

    'Do not forget to load the layout file created with the visual designer. For example:
    'Activity.LoadLayout("Layout1")
    onyx.Initialize("Onyx")

It's really nice but can I scan a local image?

DonManfred · Aug 14, 2016

1. Use a loacal url. Don´t know how to get it
2. get the bytes of the image and use

B4X:

fromVideoArray (videoArray() As Byte)

At least the second is just a guess! I just wrote the wrapper a hour ago

I´ve updated post #1 and added this important info!

Sorry I liked this post thinking it does not require any online service

Just kidding man
Thanks for all your libraries and contributions they are all great

Samuel Ramirez · Jan 29, 2017

Hi Don,

Have you an intention to implement the library for B4i?

Regards,

Samuel

I´d NOT do ANY b4i library!

So, the answer is NO.

Samuel Ramirez · Jan 30, 2017

Ok, thanks

HI,

I have tried this library --> fantastic job

Here are 2 tests with my cat, with non easy pictures :

and even less easy :

I must say that I am impressed by the accuracy of the returned tags :

Thank you for this lib !

freedom2000 · Mar 4, 2017

For the above example I have uploaded my cat on my web site.
But I really don't know how to pass a Url to access an image on my android phone...
Has anyone succeeded in doing this ?

Basicaly my idea would be to try to set up a simple cat feeder like this one
(But only for fun of course, no commercial wish).
I imagine opening the cover plate if the cat is recognized + some other "efeatures"

freedom2000 · Mar 4, 2017

I have tried to call onyx.fromVideoArray after having taken an image with CameraEx class
I wanted to pass the BytesArray but it failed : code runs but Onyx never answered

B4X:

Sub Camera1_PictureTaken (Data() As Byte)
 
    onyx.Initialize("Onyx")
    onyx.fromVideoArray(Data)
    onyx.TagsandProbability
End Sub

freedom2000 · Mar 4, 2017

Finally I have found a workaround to upload my cat from my phone...

I use httpServer library.
I have been obliged to configure my router to access my Android server, but it works, you can take a picture of your cat and give it to Onyx

freedom2000 · Mar 4, 2017

Hi,

Just for fun I have coded a small App which is a merge of HttpServer, CameraEx and Onyx lib.

Here is the result and the source code

Thanks again @DonManfred for this impressive lib

It should compile... Just change the IP Address of your router

B4X:

ub Camera1_PictureTaken (Data() As Byte)
    Dim filename As String = "1.jpg"
    Dim dir As String = File.DirInternalCache
   
    camEx.SavePictureToFile(Data, dir, filename)
    camEx.StartPreview 'restart preview
   
    'send a broadcast intent to the media scanner to force it to scan the saved file.
    Dim Phone As Phone
    Dim i As Intent
    i.Initialize("android.intent.action.MEDIA_SCANNER_SCAN_FILE", _
        "file://" & File.Combine(dir, filename))
    Phone.SendBroadcastIntent(i)
    'ToastMessageShow("Picture saved." & CRLF  & "File size: " & File.Size(dir, filename), True)
    EdtOnyx.Text = ""
    onyx.Initialize("Onyx")
    onyx.fromURL("http://YOUR_Address:5555/1.jpg")
    onyx.TagsandProbability
End Sub

Dear friends,

it not functioned. As is in this threat wrote - because of pricing and licencing. We must have API key, its true? But where I must put this key?

Best regards
p4ppc

DonManfred · Sep 23, 2018

i guess in res/strings.
See https://github.com/hanuor/onyx/blob/develop/onyx/src/main/res/values/strings.xml

You can create this with the CreateResource command in the manifesteditor.
