无法在我的应用程序中使用ai.djl.modality.cv.util.BufferedImageUtils

Question

我是AI技术的新手，.I开发了我的项目所需要的每个DJL。但是当我使用ai.djl.modality.cv.util.BufferedImageUtils的时候。我无法在我的project.It中导入它，向我展示一个错误，创建局部变量BuffredImageUtils。

Unresolved reference: BufferedImageUtils

在这里我在我的项目中添加了所有的渐进式退步

import java.awt.image.BufferedImage

@Configuration
class DjlConfig{
    class XrayTranslator: Translator<BufferedImage,Classifications> {
        override fun processInput(ctx: TranslatorContext?, input: BufferedImage?): NDList {
            var array: NDArray? = BufferedImageUtils.toNDArray(
                ctx.ndManager, input, NDImageUtils.Flag.COLOR
            )
            array = NDImageUtils.resize(array, 224).div(255.0f)
            return NDList(array)
        }

        override fun processOutput(ctx: TranslatorContext?, list: NDList?): Classifications {
            TODO("Not yet implemented")
        }

        override fun getBatchifier(): Batchifier {
            TODO("Not yet implemented")
        }

    }

}

我在这一行得到了精确的误差。

var数组: NDArray？= BufferedImageUtils.toNDArray(

无法访问DJL功能和内容

Answer 1

BufferedImageUtils已在较新版本的DJL中删除。您需要使用ImageFactory来代替：

ImageFactory factory = ImageFactory.getInstance();
# Image image = factory.fromFile(Paths.get("..."));
# Image image = factory.fromUrl("...");
Image image = factory.fromImage(bufferedImage);
NDArray array = image.toNDArray(ctx.getManager());
