Image preprocessing in Xception model

The image preprocessing process for the Xception model typically includes the following steps:

  1. Size Adjustment:
    • The Xception model expects the input image size to usually be 299x299 pixels.
  2. Color Channel Processing:
    • The Xception model expects the input to be a color image, i.e., having 3 color channels (Red, Green, Blue). If your image is grayscale (single-channel), you need to convert it into a three-channel format.
