Can anybody suggest me how can I extract segmented image in flutter . I was able to use tenserlite model
for segmentation but i don't know how i can extract that segmented image from it.
I also wanted to do image segmentation. So I did a lot of search. And I found one open source.

I developed app to remove image background using google MLKit Image. Image Segmentation does not give prices results., i studied Deeplabv3 has precise results.
link is below

i used this project example deeplab. there is not right result there are random result.

please help me to remove image background with precise result in flutter.
i will be thankful to you
I try to detect barcodes in webcam images and have problems to find small barcodes in a large image. xzing (svn trunk) fails to find the barcode in the first image (See links) even with try-harder. If I however manually crop the image (second image) it has no problem extracting the information. So it should also be possible to find the barcode in the first image.
Is there a way to tell xzing to also find smaller barcodes? Or is there already some sliding window implemented or maybe a gradient based barcode localizer?
Original: No barcode found

Cropped Version: Barcode extracted

Try different binarizers. You are probably using the one that computes a histogram over the whole image. The varied brightness causes the barcode itself to be treated as more uniform patch of black. The hybrid binarizer is more localized and likely to get the same effect as cutting out the rest of the image manually.
In my case this tip helped
Android zxing NotFoundException
It suggests adding TRY_HARDER
Hashtable<DecodeHintType, Object> decodeHints = new Hashtable<>();
decodeHints.put(DecodeHintType.TRY_HARDER, Boolean.TRUE);
result = reader.decode(bitmap, decodeHints);
I want to integrate OCR in an iOS application. I have found some helpful tutorials, specially This Article: How To: Compile and Use Tesseract (3.01) on iOS (SDK 5), helped me a lot. Now I can read plain text from any image which has a clear background. But I want to read information from an ID card which doesn't have clear background at all!
I have also found some answers regarding removing background in stackoverflow, for example: Prepare complex image for OCR, Remove Background Color or Texture Before OCR Processing and How to use OpenCV to remove non text areas from a business card?
But those solutions are not for iOS. I understand the steps, but I need an iOS example and if it is using Core Image, than it would be better for me.
I have no problem in OCR end, but my problem is to remove the background.
Initial Image:
After removing, the image should look like this:
Can you refer me an iOS example? or Is it possible to refer me an iOS example to remove all the color without Black color?
the best way to detect a card in sence is traing a cascade classifier.
Training is not a very small project. the count of the sample images should be more thank 10K.
Once you get the trained cascade classifier, you can detect the the card quickly.
The detection is very quick on iOS, but the tesseract recognition is not very fast,
I am implementing an iPhone application, in which I have implemented the following functionalities:
Select photo
Capture photo
Now I want to give a sketch effect to that photo like this one.
How could I do this?
If I may once again recommend it, my open source GPUImage framework has a built in filter that does just this. The GPUImageSketchFilter uses Sobel edge detection to highlight edges in black on images or video, leading to the exact same effect as seen in that application:
The above image was drawn from this answer, where I describe how that filter works, as well as show a couple other filter examples.
In fact, the SimplePhotoFilter example application that comes with the framework does exactly what you describe (capture a photo, apply a sketch filter to it, and save it to the photo library), so I'd start there if you want to get this up and running quickly.
OpenCV can be used to give sketch effect on image in iphone.
Refer iphone-how-to-convert-a-photo-into-a-pencil-drawing link and get helped.
Core Image filters are probably the best way to go.

I am not able to understand how to rotate the image.
I am trying to make circular progress bar.
I got a image grom preloder.
but i didn't find any thing in CSS to rotate this image.
Do i have to take the 2 or 3 images of same preloader and use setVIsible()
Plz help me to underStand this .
thanks
You don't have to use setVisible etc. If you download the file as gif and include it as any image file, that should work. Conduct a simple test to test for yourself and understand what I mean: save the gif file on your system and then open it with any browser. You will see the loading animation without any code. Basically gif file itself will take care of animation, as per specificatoin
