Crate is_photo

is-photo

Utility to determine if an image is likely a photograph or a 2D graphic, such as a logo, illustration, or digital art.

It does this by taking various statistics from the image and running them through a pre-trained logistic regression model, along with a few sure-fire heuristics.

On my test set of around 1500 images, it has a 94% accuracy rate. Feel free to submit links to additional image sets to train on in an issue!

Example

let img = image::open("test.jpg")?;

let analysis = is_photo::analyze(&img).expect("Failed to analyze image");

let is_photo = analysis.is_photo(&is_photo::STANDARD_MODEL);

Future work may include training on a larger dataset, and possibly using a full neural network instead of logistic regression.

Modules

Logistic Regression model for classification and training

Structs

Analysis

Image analysis results, most of which are used as features for the regression model to classify images as photos or vectors.

Constants

STANDARD_MODEL

Pre-trained regression model with about 94% accuracy on my test set of 1500 images.

Functions

analyze

Analyze an image and return the results.
