CnSTD是Python 3下的场景文字检测(Scene Text Detection,简称STD)工具包,支持中文、英文等语言的文字检测,自带了多个训练好的检测模型,安装后即可直接使用。CnSTD自V1.2.1版本开始,加入了数学公式检测(Mathematical Formula Detection,简称MFD)模型,并提供训练好的模型可直接用于检测图片中包含的数学公式(行内公式embedding...
A result, such as AnalyzeSentimentResult, is the result of a text analysis operation and contains a prediction or predictions about a document input. The error object, DocumentError, indicates that the service had trouble processing the document and contains the reason it was unsuccessful. Document...
# Collect the predictions here all_predictions = [] for x_test_batch in batches: batch_predictions = sess.run(predictions, {input_x: x_test_batch, dropout_keep_prob: 1.0}) all_predictions = np.concatenate([all_predictions, batch_predictions]) # Print accuracy if y_test is defined if y...
machine learning techniques in Scikit-Learn and Gensim, creating customtransformersthat can be used inside repeatable and reusablepipelines. By the end of this chapter, we will be ready to engage our preprocessed corpus, transforming documents to model space so that we can begin making predictions....
self.predictions = tf.argmax(self.scores, 1, name="predictions") 1. 2. 3. 4. 5. 其中,tf.nn.xw_plus是一个实现 矩阵乘法的一个封装方法。 1.6 loss和准确率计算 我们可以使用1.5得到的score来定义loss function。分类问题的标准损失方程为交叉熵损失方程。
At low numbers of training samples, the models’ predictions are not valid JSON objects, and the annotator had to redo annotations from scratch. At higher numbers of training samples, particularly those above 50, the intermediate model predictions required very little error correction from the annota...
Lines 2-10import our required Python packages. TheEAST_OUTPUT_LAYERSanddecode_predictionsfunction come from our implementation of the EAST text detector in our tutorial,OpenCV Text Detection. Be sure to review that lesson if you need a refresher on the EAST detection model. ...
默认为 `./predictions` -h, --help Show this message and exit. 例如可以使用以下命令对图片 examples/taobao.jpg进行检测,并把检测结果存放在目录 outputs中: cnstd predict -i examples/taobao.jpg -o outputs 具体使用也可参考文件 Makefile。 MFD or Layout Analysis 预测单个文件 使用命令 cnstd analyze ...
