predict_RF {ExpImage}

Pixel classification by Random Forest methodology (Classificacao de pixels pela metodologia Random Forest)

Description

This function classifies pixels in images from a random forest model (Esta funcao classifica pixels em imagens a partir de um modelo de random forest).

Usage

predict_RF(im,model,col="rand",plot=TRUE)

Arguments

im

: Image that will be segmented (Imagem que sera segmentada).

model

: Model adjusted by the "segmentation RF" function (Modelo ajustado pela funcao "segmentation_RF").

col

: Vector with the desired colors in the segmentation. If it's "rand" it will be random colors (Vetor com as cores desejadas na segmentacao. Se for "rand" serao cores aleatorias).

plot

: Logical value, if TRUE, the image will be displayed (Valor logico, se for TRUE a imagem sera apresentada).

Value

Returns the segmented image (Retorna a imagem segmentada).
