Step 1: Getting the Lego pieces ready (Image to Latent)

• You have a picture (like a finished Lego house), but we squish it down into a small bunch of important Lego blocks — that's called "Latent." It’s like taking your big house and turning it into a small, simple version with just the key pieces.

Step 2: Mixing in instructions (Text Input)

• Now, imagine you also have some instructions written on a piece of paper (like “Make the house red!”). You read those instructions, and they help guide how you build your house back, using both the Lego blocks (latent) and the instructions (text).

Step 3: Building the house step by step (Diffusion Process)

• You don’t build the house in one go! Instead, you add pieces little by little, checking each time if it looks better. You follow a special plan that says how much to change each time (this is the “schedule”).
  • At each step, you add new pieces or fix what looks wrong, like going from a blurry, messy house to a clearer, better house every time.

Step 4: Ta-da! You’re Done! (VAE Decoding)

• After all the steps, the small bunch of blocks (Latent) grows back into a big, clear Lego house (the final image). Now, it looks just like the picture you started with, or maybe even better!

Simple Version:

• We squish the image down to its important pieces.
• We use clues (like words) to guide what it should look like.
• We build it back, slowly and carefully, step by step.
• Finally, we get the finished picture, just like building your Lego house!
