Image transformations

Description

Performs various transformations on the image
Real time: True

Usage

• Pre-processing: Transform the image to help segmentation, the image may not retain it's properties. Changes here will be ignored when extracting features
• Image checking: Check different aspects of an image
• Feature extraction: Tools to extract features from a segmented image
• Exposure fixing: Fix image exposure, the resulting image will be used for color analysis

Parameters

• Activate tool (enabled): Toggle whether or not tool is active (default: 1)
• Select transformation (method): (default: alpha_beta)
• Apply smart transformation if (apply_case): (default: always)
• Alpha/Gamma (alpha_gamma): Alpha value for linear transformation, gamma for gamma correction (default: 100)
• Beta (brightness) (beta): (default: 0)
• Target brightness (target_brightness): (default: 0)
• Limit brightness fixing (max_delta_for_brightness): (default: 255)
• Show over an under exposed parts (show_over_under): (default: 0)
• Brightness calculation mode (brg_calc): (default: std)
• Overlay text on top of images (text_overlay): Draw description text on top of images (default: 0)

---

• output (tb_output): ('Image', 'Brightness average', 'Contrast average', 'Brightness min/max')
