-## Model description
+## Model details
 
 The abstract from the paper is the following:
 This research paper proposes a Latent Diffusion Model for 3D (LDM3D) that generates both image and depth map data from a given text prompt, allowing users to generate RGBD images from text prompts. The LDM3D model is fine-tuned on a dataset of tuples containing an RGB image, depth map and caption, and validated through extensive experiments. We also develop an application called DepthFusion, which uses the img2img pipeline to create immersive and interactive 360-degree-view experiences using TouchDesigner. This technology has the potential to transform a wide range of industries, from entertainment and gaming to architecture and design. Overall, this paper presents a significant contribution to the field of generative AI and computer vision, and showcases the potential of LDM3D and DepthFusion to revolutionize content creation and digital experiences.

-### Limitations and bias
-
-For the image generation, limitations and bias are the same as the ones from [Stable diffusion](https://huggingface.co/CompVis/stable-diffusion-v1-4#limitations)
-For the depth map generation, a first limitiation is that we are using DPT-large to produce the ground truth, hence, other limitations and bias are the same as the ones from [DPT](https://huggingface.co/Intel/dpt-large).

 ## Training data
 
 The LDM3D model was finetuned on a dataset constructed from a subset of the LAION-400M dataset, a large-scale image-caption dataset that contains over 400 million image-caption pairs.
 
 ### Finetuning
 
-The fine-tuning process comprises two stages. In the first stage, we train an autoencoder to generate a lower-dimensional, perceptually equivalent data representation. Subsequently, we fine-tune the diffusion model using the frozen autoencoder

 ## Evaluation results
 
-Please refer to Table 1 and Table2 from the [paper](https://arxiv.org/abs/2305.10853) for quantitative results.
-The figure below shows some qualitative results comparing our method with (Stable diffusion v1.4)[https://arxiv.org/pdf/2112.10752.pdf] and with (DPT-Large)[https://arxiv.org/pdf/2103.13413.pdf] for the depth maps

+### Quantitative results
+
+The table below shows the quantitative results of text-conditional image synthesis on the 512 x 512-sized MS-COCO dataset with 50 DDIM steps.
+
+|Method      |FID ↓|IS ↑        |CLIP ↑      |
+|------------|-----|------------|------------|
+|SD v1.4     |28.08|34.17 ± 0.76|26.13 ± 2.81|
+|SD v1.5     |27.39|34.02 ± 0.79|26.13 ± 2.79|
+|LDM3D (ours)|27.82|28.79 ± 0.49|26.61 ± 2.92|  
+
+Our model is on par with the Stable Diffusion models with the same number of parameters (1.06B). IS and CLIP similarity scores are averaged over 30k captions from the MS-COCO dataset.
+
+The following table shows the evaluation results of depth evaluation comparing LDM3D and DPT-Large with respect to ZoeDepth-N that serves as a reference model.
+
+|Method   |AbsRel|RMSE [m]|
+|---------|------|--------|
+|LDM3D    |0.0911|0.334   |
+|DPT-Large|0.0779|0.297   |

+### Qualitative results
+
+The figure below shows some qualitative results comparing our method with [Stable Diffusion v1.4](https://arxiv.org/pdf/2112.10752.pdf) and with [DPT-Large](https://arxiv.org/pdf/2103.13413.pdf) for the depth maps ![qualitative results](qualitative_results.png).
+
+## Ethical Considerations and Limitations
+
+For image generation, the [Stable Diffusion](https://huggingface.co/CompVis/stable-diffusion-v1-4#limitations) limitations and biases apply. For depth map generation, a first limitiation is that we are using DPT-large to produce the ground truth, hence, other limitations and biases from [DPT](https://huggingface.co/Intel/dpt-large) are applicable.
+
+## Caveats and Recommendations
+
+Users (both direct and downstream) should be made aware of the risks, biases and limitations of the model.
