您可以尝试JavaCPP-presets。

在build.gradle上添加一些依赖项：

dependencies {
    ...
    implementation group: 'org.bytedeco.javacpp-presets', name: 'opencv', version: '4.1.2-1.5.2'
    implementation group: 'org.bytedeco.javacpp-presets', name: 'opencv', version: '4.1.2-1.5.2', classifier: "android-arm"
    implementation group: 'org.bytedeco.javacpp-presets', name: 'opencv', version: '4.1.2-1.5.2', classifier: "android-arm64"
    implementation group: 'org.bytedeco.javacpp-presets', name: 'opencv', version: '4.1.2-1.5.2', classifier: "android-x86"
    implementation group: 'org.bytedeco.javacpp-presets', name: 'opencv', version: '4.1.2-1.5.2', classifier: "android-x86_64"
}

您可以使用org.bytedeco.javacpp.helper.opencv_imgproc或org.opencv.imgproc.Imgproc
