Overview

Image-Processing-CLI-in-Rust

CLI for processing images in Rust. Some implementation is custom and for some functionality it uses 3rd party libraries.

This project uses following libraries:

https://github.com/PistonDevelopers/image

Processed images are being stored in the same folder as the source image using the name of the source image with an appended suffix.

Source: hotelroom.jpg

Copy: hotelroomCopy.jpg

Blur: hotelroomBlur.jpg

Generated histograms are also stored this way.

Implemented functions

Binary treshold -o binaryTreshold -v 200
(NAIVE) Histogram for colors (RGB) -o histogram
(NAIVE) Histogram for grayscale images -o histogramGrayscale
Average color -o average
Copy: -o copy
Thumbnail: -o thumbnail -v 96
blur: -o blur -v 4.0
brighten: -o brighten -v 10
huerotate: -o huerotate -v 10
contrast: -o contrast -v 20.0
grayscale: -o grayscale
invert -o invert

Examples

Copy image

ipcli -o copy --image "D:\Image\hotelroom.jpg"

Create a thumbnail

ipcli -o thumbnail -v 96 --image "D:\Image\hotelroom.jpg"

Generate a historgram of colors

ipcli -o histogram -i "D:\Image\hotelroom.jpg"

Basic CLI for image processing

USAGE:
    ipcli [OPTIONS] --image <FILE> --operation <operation>

FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information

OPTIONS:
    -i, --image <FILE>             Opens specified image file and uses it for transformations.
    -o, --operation <operation>    Specifies operation to be done on the image
    -v, --value <value>            Value for the transformation. To see what values are needed, check the
                                   documentation.
                                   ```

Added Canny Edge Detector

This is an implementation of an edge detector based on the Canny Edge Detection Algorithm. The new operation is called "canny" and it takes 3 floats: sigma (Gaussian blur parameter to reduce noise), min_val (parameter to remove pixels that aren't "strong" enough edge pixels), and max_val (parameter that keeps pixels that are "strong" enough edge pixels).

Refactor code, fix bugs, add example to README

The new code doesn't handle this case: https://github.com/spejss/Image-Processing-CLI-in-Rust/blob/9545f0e68ca6761c6c9387636cfeb5be95109591/src/main.rs#L297 . I don't think the code in question was ever reachable.
