- Model included in
/model/were converted to TFJS Graph model format from the original repository
Model descriptors and signature have been additionally parsed for readability - Model itself uses dynamic input sizes
- Parsing implementation in
nudenet.jsdoes not follow original
and is implemented using native TFJS ops and optimized for JavaScript execution - Code also includes simple bluring function for exposed body parts in the input image
- Example implementation is for NodeJS
but can be used in Browser environments by changing tfjs dependencies and image loader function
Structure of the return object:
{
input: {
file: String,
width: Number,
height: Number,
},
person: Boolean, // is person detected?
sexy: Boolean, // is person considered sexy?
nude: Boolean, // is person considered nude?
parts: Array<{ // array of detected body parts
score: Number, // confidence in detection
id: Number,
class: String, // label for body part
box: Number[], // [x, y, width, height]
}>,
}Where class can be :
const labels = [ // class labels
'exposed anus',
'exposed armpits',
'belly',
'exposed belly',
'buttocks',
'exposed buttocks',
'female face',
'male face',
'feet',
'exposed feet',
'breast',
'exposed breast',
'vagina',
'exposed vagina',
'male breast',
'exposed male breast',
