interactive_objectDetection: Interactive object detection

In biopixR: Extracting Insights from Biological Images

Interactive object detection

Description

This function uses the objectDetection function to visualize the detected objects at varying input parameters.

Usage

interactive_objectDetection(img, resolution = 0.1, return_param = FALSE)

Arguments

img	image (import by importImage)
resolution	resolution of slider
return_param	if TRUE the final parameter values for alpha and sigma are printed to the console (TRUE | FALSE)

Details

The function provides a graphical user interface (GUI) that allows users to interactively adjust the parameters for object detection:

• Alpha: Controls the threshold adjustment factor for edge detection.

• Sigma: Determines the amount of smoothing applied to the image.

• Scale: Adjusts the scale of the displayed image.

The GUI also includes a button to switch between two detection methods:

• Edge Detection: Utilizes the edgeDetection function. The alpha parameter acts as a threshold adjustment factor, and sigma controls the smoothing.

• Threshold Detection: Applies a thresholding method, utilizing SPE for background reduction and the threshold function. (No dependency on alpha or sigma!)

Value

Values of alpha, sigma and the applied method.
