Bitmask

Generate JSON representations of bitmasks from image selections for machine learning applications.

DEMO

This uses Bootstrap, jQuery, and fabric.js

Data Output

Bitmask outputs a JSON string representing the area selection of an image. All the arrays are 0-based (e.g an image which is 300px in height will be represented as a multidimensional array of length 299, assuming one of the [y,x] output formats are selected in the options menu.)

Formats

Format	Description
Pixel Coordinate Array [y,x]	A representation of the selected area in which x coordinates are contained within an array who's index corresponds to a y coordinate.
Pixel Coordinate Array [x,y]	A representation of the selected area in which y coordinates are contained within an array who's index corresponds to an x coordinate.
Bitmask Array [y,x]	A representation of the selected area in which x coordinates are contained within an array who's index corresponds to a y coordinate. Selected pixels are represented by a 1, while the rest are represented by a 0.
