In Pechli-Lab/SurvdigitizeR: Digitizing Survival Curves

fig_clean Removes color values close to white, also possible to remove text on plot, useful for gridlines on KM curves

Description

fig_clean Removes color values close to white, also possible to remove text on plot, useful for gridlines on KM curves

Usage

fig_clean(fig.hsl, bg_lightness = 0.1, attempt_OCR = F, word_sensitivity = 30)

Arguments

fig.hsl	array of pixels in HSL format (hue/saturation/lightness)
bg_lightness	a lightness threshold value between 0 and 1; every pixel with lightness > bg_lightness is considered background and removed (default: 0.1).
attempt_OCR	a logical indicating whether to attempt text recognition (default: False)
word_sensitivity	A sensitivity percentage value for word recognition, potential pixel patterns are considered words if confidence > word_sensitivity (default: 30)

Value

fig.df: a dataframe with x,y and h,s,l values for each remaining pixel

Examples

# fig_clean(fig.hsl = figure, bg_lightness = 0.1, attempt_OCR = T, word_sensitivity = 30)
