如何以逆灰度保存圖像？

Question

誰能告訴我如何使用 scipy.misc.imsave.Using 下面的代碼以反灰度保存圖像，我只能以灰度模式保存圖像，但我的分類任務需要反灰度圖像

            data = next(generator_queues[j])

            assert data.shape == target_shape, "Shape mismatch {} vs {}".format(data.shape, args.shape)

            file_name = os.path.join(args.target, language, "{}.png".format(i))

            scipy.misc.imsave(file_name, np.squeeze(data))

Answer 1

嘗試： np.squeeze(255 - data)

    data = next(generator_queues[j])

    assert data.shape == target_shape, "Shape mismatch {} vs {}".format(data.shape, args.shape)

    file_name = os.path.join(args.target, language, "{}.png".format(i))

    scipy.misc.imsave(file_name, np.squeeze(255 - data)) # if not normalised else 1 - data
