Vision-Language Models: How ViT, CLIP, and Qwen2.5-VL Process Images

By PulseAugur Editorial · [1 sources] ·

A recent analysis delves into the internal workings of Vision-Language Models (VLMs), explaining their three-stage image processing pipeline. This process involves a Vision Transformer (ViT) for patch slicing and merging, a Dual Spatial Compass using rotary position embeddings for understanding 2D and 3D spatial data, and cross-modal attention with Visual Contrastive Decoding (VCD) to improve object grounding and reduce hallucinations. Experiments demonstrated that models like OpenAI's CLIP can be fooled by simple typographic attacks, misclassifying an apple with an "iPod" label as an electronic device. AI

IMPACT Provides insight into VLM image processing, highlighting vulnerabilities and potential improvements in object recognition.
