Use image_features instead of patch_tokens

[ByChelsea]

Hi, I'm glad you're interested in our work.

Image_features contain the global information of an image, which is the sum of all the local detailed information. To perform anomaly segmentation, specific detailed information at each position in the image is often required, which cannot be directly reflected through image_features alone.

Therefore, I believe that it is not possible to obtain anomaly maps solely through image_features and text_features. However, image_features do contain certain valuable information. You can consider how to use this information in addition, instead of completely discarding patch_tokens.
