ERROR | Corrupt JPEG data: 111 extraneous bytes before marker 0xd9...

问题描述
Corrupt JPEG data: 1 extraneous bytes before marker 0xdb
libpng warning: iCCP: known incorrect sRGB profile
Premature end of JPEG file

使用opencv(python)读取图片时，报如上错误，据说是因为图片破损。try_except未能捕获该警告。该部分代码如下：

img = cv2.imread(img_path)
if img is None:
img = np.zeros(shape=(224, 224, 3), dtype=np.uint8)
img = cv2.cvtColor(img, cv2.COLOR_BGR2RGB)
img = Image.fromarray(img)

解决方案
使用PIL的读取函数。修改如下：

img = None
try:
img = Image.open(img_path).convert("RGB") #1
except:
pass
if img is None:
img = np.zeros(shape=(224, 224, 3), dtype=np.uint8)
img = Image.fromarray(img)

其中#1处添加.convert("RGB")，因为数据集含有RGBA(png)或者灰度图片，所有要进行类型转换。

如遇到如下警告，可使用warnings（warnings.filterwarnings(“ignore”)）忽略。

PIL Palette images with Transparency expressed in bytes should be converted
