Sata

Simple cross-platform image processing toolkit

Introduction

This is an image processing toolkit written in Scala, which will contain many image processing programs based on opencv and yolo, etc.

List

Detect target objects in images

Usage

Sata uses opencv 4.8.1, So you need to make sure that opencv-481.jar is in your system's classpath, Or you can specify its path, for example:

-Djava.library.path=/usr/local/share/java/opencv4/

For developers, you need to create a new directory lib in the project root, Then put opencv-481.jar into it. This is for integration with IDE.

Detect target objects in images

object ObjectDetection extends sata.Sata[String, Mat, Mat, Unit]:
  val input: Input = Input("./src/test/scala/com/muqiuhan/sata/image/object_detection/test.jpg")
  val processor: Processor = Processor(
    input.input(input.letterbox),
    "./src/main/scala/com/muqiuhan/sata/image/object_detection/yolov7-d6.onnx",
    input.letterbox
  )
  
  val output: Output = Output(processor.process())

then

ObjectDetection.run()

Enhancement

Histogram equalization
Laplacian
Log transformation
Gamma transform

object HistogramEqualization extends sata.Sata[String, Mat, Mat, Unit] {
  val input: Input = Input("./src/test/scala/com/muqiuhan/sata/image/enhancement/test1.jpg")
  val processor: HistogramEqualizationProcessor = HistogramEqualizationProcessor(input.image)
  val output: Output = Output(processor.process())
}

Or you can combine them:

object HistogramEqualizationWithGammaTransform extends sata.Sata[String, Mat, Mat, Unit] {
  val input: Input = Input("./src/test/scala/com/muqiuhan/sata/image/enhancement/test1.jpg")
  val processor1: LaplacianProcessor = LaplacianProcessor(input.image)
  val processor: GammaTransformProcessor = GammaTransformProcessor(processor1.process())
  val output: Output = Output(processor.process())
}
