This thesis introduces a novel approach to subject-driven image generation, advancing the field by overcoming the limitations of traditional text-to-image diffusion models. Our method employs a model that generates images from reference images without the need for language-based prompts. By integrating our proposed module named as visual detail preserving module, the model captures intricate visual details and textures of subjects, addressing the common challenge of overfitting associated with a limited number of training samples. We further refine the model's performance through a modified classifier-free guidance technique and feature concatenation, enabling the generation of images where subjects are naturally positioned and harmonized within diverse scene contexts. Quantitative assessments using CLIP and DINO scores, complemented by a user study, demonstrate our model's superiority in fidelity, editability, and overall quality of generated images. Our contributions not only show the potential of leveraging pre-trained models and visual patch embeddings in subject-driven editing but also highlight the balance between diversity and fidelity in image generation tasks.
