Extracting features like colors and shapes simplifies matching and speeds up search, as shown in step 2 of the execution_table.

How does the engine decide which images to show first?

It ranks matched images by relevance and similarity, as seen in step 4 where top 5 matches are selected.

Full Transcript

Visual search optimization works by letting a user upload or take a photo. The search engine then analyzes the image to find important features like colors and shapes. It compares these features to a database of indexed images to find matches. The engine ranks these matches by how similar they are and shows the top results to the user. Finally, the user can click a result to visit the related website or take action. This process helps users find products or information using pictures instead of words.
