下面是使用Python代码示例演示如何使用Amazon Textract和Amazon Rekognition DetectText:
使用Amazon Textract进行文本提取:
import boto3
def extract_text_from_image(image_path):
client = boto3.client('textract', region_name='us-west-2') # 创建Textract客户端
with open(image_path, 'rb') as image_file:
image_bytes = image_file.read() # 读取图像字节数据
response = client.detect_document_text(Document={'Bytes': image_bytes}) # 发送图像字节数据进行文本提取
text = ''
for item in response['Blocks']:
if item['BlockType'] == 'LINE':
text += item['Text'] + '\n'
return text
image_path = 'image.jpg'
text = extract_text_from_image(image_path)
print(text)
使用Amazon Rekognition DetectText进行文本检测:
import boto3
def detect_text_from_image(image_path):
client = boto3.client('rekognition', region_name='us-west-2') # 创建Rekognition客户端
with open(image_path, 'rb') as image_file:
image_bytes = image_file.read() # 读取图像字节数据
response = client.detect_text(Image={'Bytes': image_bytes}) # 发送图像字节数据进行文本检测
text = ''
for item in response['TextDetections']:
if item['Type'] == 'LINE':
text += item['DetectedText'] + '\n'
return text
image_path = 'image.jpg'
text = detect_text_from_image(image_path)
print(text)
以上示例代码演示了如何使用Amazon Textract和Amazon Rekognition DetectText进行文本提取和检测。请确保已安装并配置了Boto3库,并将图像路径替换为您自己的图像路径。
