Feature Overview
Cloud Infinite provides general matting through the AIPicMatting API. It can detect entity information in a picture, automatically split the background, generate picture that only contain entity information, and can support persistent processing, processing in the cloud, and processing during download.
Use Limits
When using this API, please first confirm the relevant restrictions. For details, see Specifications and Limits.
Authorization Guide
When used with a sub-account, corresponding permissions must be granted. For COS permissions, please refer to Cloud Object Storage. For other CI permissions, please refer to Cloud Infinite.
Processing during download: Set action to cos:GetObject, ci:CreateS3AIPicMattingJob in the authorization policy.
Processing during upload: Set action cos:PutObject in the authorization policy
Processing in the cloud: Set the action to cos:GetObject and cos:PutObject in the authorization policy. (Note: GetObject corresponds to the source file, and PutObject corresponds to the transferred file).
Service Activation
Using this feature requires enabling Cloud Infinite in advance and binding a bucket. For details, see Binding CI.
Fee Description
This API is a paid service. The incurred fees will be collected by Cloud Infinite. For detailed billing information, see Content Recognition Expenses.
Processing Method 1: Processing during Download
Request
 Original images are stored in COS.  
GET /<ObjectKey>?ci-process=AIPicMatting HTTP/1.1
Host: <BucketName-APPID>.cos.<Region>.myqcloud.com
Date: <GMT Date>
Authorization: <Auth String>
 Original images come from other links.
GET /?ci-process=AIPicMatting&detect-url=<detect-url> HTTP/1.1
Host: <BucketName-APPID>.cos.<Region>.myqcloud.com
Date: <GMT Date>
Authorization: <Auth String>
Processing Parameter
Operation name: AIPicMatting
Parameter
Meaning
Type
Required
ObjectKey
Object filename, for example: folder/document.jpg
String
Yes
ci-process
Cloud Infinite processing capability, general matting is fixed as AIPicMatting
String
Yes
detect-url
You can fill in the detect-url to process any publicly accessible image link. If detect-url is not specified, the backend will process the ObjectKey by default. If detect-url is filled in, the backend will process the detect-url link, and there is no need to fill in the ObjectKey. Example of detect-url: http://www.example.com/abc.jpg, which needs to be UrlEncoded and processed into http%25253A%25252F%25252Fwww.example.com%25252Fabc.jpg.
String
No
center-layout
Center the subject for matting; display centered when the value is 1, take no action when the value is 0, default is 0
Integer
No
padding-layout
Add padding to all four sides of the processed image, in the form of padding-layout = <dx>x<dy>. The left and right sides are padded by dx pixels each, while the top and bottom sides are padded by dy pixels each. For example: padding-layout = 20x10
Default does not perform blanking operation, maximum value of dx and dy is 1000 pixels.
String
No

Note:
Authorization: Auth String. For details, see Request Signature documentation.
Request
Request Header
This API uses common request headers. For details, see Common Request Headers documentation. 
 In addition to the common request headers, the following headers are required:
Header Name
Description
Type
Pic-Operations
Parameters for image operations
String
Pic-Operations is a JSON format string. The specific parameters are as follows:
Parameter
Type
Required
Description
is_pic_info
Int
No
Whether to return original image information, 0 for no return, 1 for return, default is 0
rules
Array
No
Processing rules, content recognition only supports one rule
Each item in the rules (JSON array) has the following specific parameters:
Parameter
Type
Required
Description
bucket
String
No
Destination bucket name for storing results, format is BucketName-AppId. If not specified, it defaults to the current bucket.
fileid
String
Yes
Storage path and name of the processed file. Name rule description:
For example, the source file path and name are: /p1/test1.jpg
Absolute paths start with /, for example, when the fileid value is /p2/test2.jpg, it means a file named test2.jpg is stored in the p2 folder.
Relative paths do not start with /, for example, when the fileid value is p2/test2.jpg, it means a new p2 folder is created in the p1 folder, and then a file named test2.jpg is stored in the p2 folder.
Do not end with /, otherwise an empty filename will occur.
If you want the repaired image to overwrite the original image, set the fileid field to <ObjectKey>
rule

Yes
Fixed as: ci-process = AIPicMatting, other processing parameters refer to during download
Request Body
The request body contains the original image to be processed.
