What are the ways to initiate a REST API request?
Answer:
Explanation:
C URL: command line tool used to perform various URL operations and transmit information. C URL acts as an HTTP client, can send messages to the server and receive responses, suitable for debugging interface coding: call the interface through coding, assemble request messages, and send and process request messages. REST clients Mozilla and Google Chrome both provide REST graphical plug-ins to send and process request messages.
NEW QUESTION # 305
Which of the following descriptions of the bimodal adaptive threshold segmentation method are correct? (Multiple choice)
- A. The bimodal method divides the image into foreground and background according to the grayscale characteristics of the image. The larger the inter-class variance between the foreground and the background, the greater the difference between the two parts that make up the image.
- B. If the grayscale histogram of the image is very flat or has multiple peaks, the bimodal method cannot be used to obtain a suitable threshold.
- C. Histogram bimodal method is an easy-to-understand adaptive threshold algorithm
- D. If the image grayscale histogram is obviously bimodal, the grayscale value corresponding to the valley between the two peaks is selected as the threshold for image segmentation.
Answer: A,B,C,D
