Extract Image Data

Extracts table data from an image based on tabular input data

Algorithms:

• integrate

  Computes the integral on all points in a square between twocorner points,

  must have an integral image as input.Operates on each channel separately

  start x:

  Column containing starting points on X axis for integral

  start y:

  Column containing starting points on Y axis for integral

  end x:

  Column containing ending points on X axis for integral

  end y:

  Column containing ending points on X axis for integral

• pixel values

  Extracts the pixel values at positions given by X and Ytable rows

  x:

  Column containing X coordinates of the points to extract

  y:

  Column containing Y coordinates of the points to extract

Inputs:

source_im : image

Source image to extract data from

source_table : table

Table with parameters for data extraction

Outputs:

result : table

Table with results

Input ports:

source_im:
