Midjourney 高频使用场景 稳定输出人物角色 + 给人物换装 详细实操教程

In this introductory paragraph, the speaker, referred to as '熊哥' or 'Brother Bear', welcomes the audience to an AI class focused on a common use case of AI in e-commerce: changing the outfits of models in product images. The importance of images in conversion rates for online products is emphasized, and the potential for increased efficiency and quality of work with AI is highlighted. The speaker then proceeds to a practical demonstration, starting with a hypothetical scenario of selling a red T-shirt to an overseas market, and outlines the steps to use AI for this purpose. The process involves using a trained AI model to generate images based on specific prompts, which are then used to create product images without the need for physical photography.

The second paragraph delves into the technical aspects of using AI to maintain a consistent model appearance across different generated images. The speaker explains the use of the Image Weight (IW) command, which controls the similarity of the generated images to a reference image. The IW value can range from 0 to 2, with a higher value resulting in a closer resemblance to the reference image. The speaker demonstrates how to use the IW command with a value of 2 to ensure that the generated images closely match the original model image. The paragraph also includes a comparison between images generated with the default IW value and those with the IW value set to the maximum, showcasing the significant difference in maintaining the model's likeness.

In the final paragraph, the focus shifts to changing the model's outfit using the seed command. The seed value, likened to a seed in gardening, influences the initial set of generated images. The speaker guides the audience through the process of changing the model's T-shirt color from pink to white by adjusting the seed value and keeping the image weight (IW) at its highest. The paragraph illustrates the expected outcome of a stable model appearance with a changed outfit and compares the results of using the seed value alone versus in combination with a high IW value. The speaker concludes the tutorial by demonstrating how to achieve the desired outcome of a consistent model image with different outfits, and thanks the viewers for their attention.
