Getting Started

Endpoint

• https://api.topazlabs.com/image/v1/sharpen/async

  • model — "Portrait"

Endpoint-Specific Parameters

• denoise_strength — decimal between 0 and 1, default 0.5

  • Removes noise from the image.

• face_enhancement — boolean

  • Leverages our face recovery model to enhance faces.

• face_enhancement_strength — decimal between 0 and 1

  • Sets the strength of the face recovery.

• face_enhancement_creativity — decimal between 0 and 1

  • Choose realistic or creative face recovery.

• subject_detection — "All", "Foreground", or "Background"

  • Choose where enhancements are applied.

These parameters should be appended as key-value fields in the form-data request bodies (i.e. alongside the model, output_height, and face_enhancement etc. fields). Any parameters not explicitly provided are automatically configured by our auto-parameter model. Extra parameters provided that are not supported are ignored.

Model-Specific Parameters

• sharpen_strength — decimal between 0 and 1, default 0.5

• opacity — decimal between 0 and 1, default 1.0

When calling "Wildlife" or "Portrait", If the user does not specify a value for any of the above parameters, it will automatically calculate the optimal settings for sharpening based on the technical quality of the input (effectively the same as calling "Auto Sharpen").

Resolution Limits

• input — 512 MP

• output — 512 MP
