我可以使用Tensorflow转换/解码二进制的JPEG文件吗？

Question

I'm sending a JPEG file into an AWS Lambda function as binary in a POST request body, and I was wondering if Tensorflow has a way to convert this binary into an image that could be passed into:

tf.image.encode_jpeg()  

Any help would be greatly appreciated.

To convert a JPEG image to a tensor, you need to call tf.image.decode_jpeg() . The following code should work:

queue = tf.train.string_input_producer(['image.jpg'])
reader = tf.WholeFileReader()
_, jpg_data = reader.read(queue)
tensor = tf.image.decode_jpeg(jpg_data)
