blinkinput-android's Issues

EXTRAS_SHOW_OCR_RESULT does not work

I tried adding this code :
intent.putExtra(BlinkOCRActivity.EXTRAS_SHOW_OCR_RESULT, false);

But when the activity BlinkOCRActivity starts, the preview(green box with text) is still visible.

Get Quadrilateral size and position

Hi,

I implemented a custom Activity and embed a RecognizerView in a FrameLayout.

However, the end result I want to achieve is to have a static Quadrilateral in the middle of the screen (using QuadViewPreset.DEFAULT_FROM_SCAN_CARD_ACTIVITY), where the area outside or surrounding the Quad is blurred/darkened and the area within the Quad is fully transparent, showing the actual display from RecognizerView.

So far I have managed to overlay a view on top of RecognizerView, all that is left is for me to "cut the quadrilateral hole" in the middle of my overlay view, however, I am not able to get any information on the presenting Quad.

Is there any API which provides a way of getting the Quad size and position for me to setup my overlay view? Or is there a way for me to achieve my end result without having to use overlays?

Custom Id Identity - Cordova Plugin Blink ID

Hi, I am using ionic 1, I need to read an area of the Mexican credential "CURP", but I have not been able to find a way to do it, nor in what file can I integrate this functionality. I do not know if there is a function that allows me to define the area to be read?

BicParserSettings to go along with IbanParserSettings

Hi,

Are you planning on implementing Bank Identifier Code recognition to go along with Iban recognition ?

These would go quite well together for, say, fetching SEPA information via OCR.

I've tried with a RegexParserSettings, but formattings for BIC number are too disparate so that a regex could do the job.

I've also considered the possibility of extending OcrParserSettings, but that seems like to much work if you're going to release one some time soon.

Thanks.
Regards.

Can't autofocus with webcam camera in emulator

Before opening an issue, check that you are using the latest version of the BlinkInput SDK.

Also, make sure your issue isn't on the list of common problems.

Description

I'm using a MacBook Pro (13-inch, 2017) running an emulated device (Pixel 3 on api 28) with both the back and front camera using my webcam:

When I start the application and try to use the regex parser I get com.microblink.hardware.camera.AutoFocusRequiredButNotSupportedException: Autofocus is required, but not supported on this device in the logs and on the screen of the emulated device:

I suspect this is because the webcam doesn't support autofocus but I'm not entirely sure.

Environment Details

BlinkInput version: Not sure how to find version, here's the commit I'm on: 9019ee8

Device model: Emulated Pixel 3

Device Android version: 28

Device ABI (processor architecture, e.g. ARMv7): Unsure

Fixed Detector Region - MinimumCharHeight

Hi,

i am currently using your latest android code and modified the BlinkInputTemplatingSample to work with the type of card i am scanning:

mDocumentDetector = new DocumentDetector( DocumentSpecification.createFromPreset(DocumentSpecificationPreset.DOCUMENT_SPECIFICATION_PRESET_ID1_CARD));

Now i seem to be unable to find a way to have the scanning region ( and overlay) fixed (or at least set a minimum size).
I want to achieve that the user places the camera as close as possible to the card to be scanned as it contains some very small text.

Also is there an example on how to use setMinimumCharHeight ?
There are parts on the card i don't want the engine to recognize ( < 7 pt font size, white on blueish gradient) that are very close to the regions i need to have recognized ( 7pt, black/darkgrey on white).
How can i achieve a faster and more optimized scanning process?

capture image

i want to add a button so that user can capture image at any point, please suggest me where i have to make changes for FullScreen OCR.

Applying black and white filter

Hi,

I'm having trouble detecting color texts with blinkOCR, and I think applying black / white filter to camera will help. Is there a way to apply this in blinkOCR's BlinkInputSegmentDemo app?

Problem on handwritten text recognition

So far we have got some troubles on recognising handwritten texts. Are there any method we can improve the handwriting recognition or any feature related to that in the blinkOCR's BlinkInputSegmentDemo app?

native library with phonegap

Hi,

First of all, thank you for this great library!

Is it possible to use blinkocr in phonegap project?
If it is, is there something in particular about integration I should know about or it's standard procedure?

SegmentScanActivity customization

Hi,

I was wondering if there was any way to customize the SegmentScanActivity layout.
Specifically, I'd like to customize the validation layout (the green part) by moving the validation button to the bottom/end or bottom/start of the validation layout (This button, positionned in the middle of the screen, is not very practical to use in landscape mode).

Is that doable ?

Thanks.

Regards.
