问题 I'm testing some function in Hololens. Want to know whether it is possible to use any of object detection/text recognition in Hololens? 回答1: Here's a great blog post by one of my fellow Microsoft MVPs... :) "Labeling Toy Aircraft in 3D space using an ONNX model and Windows ML on a HoloLens" Ping me if you hit any snags -- awesome stuff! http://dotnetbyexample.blogspot.com/2019/01/labeling-toy-aircraft-in-3d-space-using.html 回答2: Hololens 1 doesn't natively support object detection, you'll

问题 I'm scanning a lot of A3 documents using a standard Brother A3 Multifunction and then use FineReader Pro for OCR'ing the images. However, I'm getting a lot of errors in the characters recognized, and lots of non-alphanumeric strange characters. Can someone give me any tips for programmatically improving the OCR accuracy, either pre-processing on the scanned images, or post-processing on the recognized text? Edit: Find a sample pdf. It includes some sample images from which I get the poorest

问题 This question has been asked severally and only suggestions are made. Ill comprehend every suggestion hopefully. the dependency is defined in the manifest <meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version"/> <meta-data android:name="com.google.android.gms.vision.DEPENDENCIES" android:value="ocr" /> and added on the app level compile 'com.google.android.gms:play-services-vision:9.8.0' The test device has sufficient storage which is

问题 I am working on an OCR system. A challenge that I'm facing for recognizing the text within ROI is due to the shakiness or motion effect shot or text that is not focus due to angle positions . Please consider the following demo sample If you notice the texts (for ex. the mark as a red), in such cases the OCR system couldn't properly recognize the text. However, this scenario can also come on with no angle shot where the image is too blurry that the OCR system can't recognize or partially

问题 I am trying to identify paragraphs of text in a .pdf document by first converting it into an image then using OpenCV. But I am getting bounding boxes on lines of text instead of paragraphs. How can I set some threshold or some other limit to get paragraphs instead of lines? Here is the sample input image: Here is the output I am getting for the above sample: I am trying to get a single bounding box on the paragraph in the middle. I am using this code. import cv2 import numpy as np large = cv2
