v1 API Endpoints (deprecated)

Overview

API URL: https://api.celantur.com/v1/

Celantur Cloud API supports only images at the moment. Support for videos will be added soon.

Upload image

POST https://api.celantur.com/v1/file

Upload image that is processed with the specified method.

The payload is limited to 4.45 MB. This limitation will be removed in the upcoming weeks.

Query Parameters

Name
Type
Description

method*

String

Specifies anonymization method:

blur, pixelate, blacken, detect

detect generates only binary and instance segmentation masks and metadata. No anonymized image will be generated.

Default: blur

debug

Boolean

Print bounding boxes and segmentation masks of detected objects on the image.

Default: false

score

Boolean

Print the detection scores of objects on the image. Works only if debug is true

face

Boolean

Specifies whether faces should be anonymized/detected.

license-plate

Boolean

Specifies whether license plates should be anonymized/detected.

person

Boolean

Specifies whether persons should be anonymized/detected.

vehicle

Boolean

Specifies whether vehicles should be anonymized/detected.

bbox

Boolean

Anonymize bounding boxes of objects (instead of segmentation).

ignores

String

Specifies pixel coordinates of areas on the image in which no anonymization will be applied (as JSON).

Example:

[{"topLeftX":182, "topLeftY":154,

"width":2000,

"height":2000}]

mask-scale

Number

Specifies the ratio at which the mask file will be scaled down, range between 0 .. 100.

Default: 100

save-mask

String

Specifies whether only mask files should be generated. This speeds up processing time by not creating an anonymized image:

all, binary, instance

detect generates only binary and instance segmentation masks and metadata. No anonymized image will be generated.

Default: all

quality

Number

Specifies image quality of anonymized images in JPEG format: 0 .. 100

Default: 90

compress-level

Number

Specifies image compression level of anonymized images in PNG format.

Default: 5

webhook

String

A webhook URL to which a POST request is sent to after successful processing.

kernel-size-face

Number

Default: 0.35

kernel-size-person

Number

Default: 95

kernel-size-license-plate

Number

Default: 0.5

kernel-size-vehicle

Number

Default: 61

face-anonymization-gradient-start

Number

Default: 0.3

face-anonymization-gradient-stop

Number

Default: 0.0

license-plate-anonymization-gradient-start

Number

Default: 0.3

license-plate-anonymization-gradient-stop

Number

Default: 0.0

}

Correctly encode strings for query parameters

When setting format, ignores and webhook values, strings must be encoded.

String encoding in Python
webhook_url = 'https://example.com/webhook/dev?sender=celantur&approve=always'

# encode the URL you want to send the webhook to
# returns 'https://example.com/webhook/dev?sender=celantur%26approve=always'
webhook_url_encoded = webhook_url.encode()

See further string encoding examples in Java, C#, JavaScript and cUrl.
