While implicit function methods capture detailed clothed shapes, they require aligned shape priors and or are weak at inpainting occluded regions given an image input. SMPL, instead offer whole body shapes, however, are often misaligned with images. In this work, we propose a novel pipeline composed of a probabilistic SMPL model and point cloud diffusion for pixel-aligned detailed 3D human reconstruction under occlusion. Multiple hypotheses generated by the probabilistic SMPL method are conditioned via continuous 3D shape representations. Point cloud diffusion refines the distribution of 3D points fitted to both the multi-hypothesis shape condition and pixel-aligned image features, offering detailed clothed shapes and inpainting occluded parts of human bodies.

We exploit the mathematical modeling of the visual cortex mechanism for border completion to define custom filters for CNNs. We see a consistent improvement in performance, particularly in accuracy, when our modified LeNet 5 is tested with occluded MNIST images. Keywords: Convolutional Neural Networks Visual Cortex 1 Introduction Visual perception has evolved as a fundamental tool for living organisms to extract information from their surroundings and adapt their behavior. However, encoding visual information presents several challenges. One major issue is occlusion, i.e. an object's outline is partially hidden by an obstacle.

The idea is to generate the same image through the model for a given sample image. The application is to use the model architecture and complete the occluded(half-filled) image. A basic encoder-decoder and deep CNN encoder-decoder models are implemented from scratch, trained, and analysed on three datasets. The Analysis is also on finding a good size hidden representation of the image for every dataset, which can be used for applications. Some well-known approaches for image generation are Autoencoders, Generative Adversarial Networks(GANs), Auto-Regressive models(PixelRNN, PixelCNN), DRAW.

Semantic inpainting is the task of inferring missing pixels in an image given surrounding pixels and high level image semantics. Most semantic inpainting algorithms are deterministic: given an image with missing regions, a single inpainted image is generated. However, there are often several plausible inpaintings for a given missing region. In this paper, we propose a method to perform probabilistic semantic inpainting by building a model, based on PixelCNNs, that learns a distribution of images conditioned on a subset of visible pixels. Experiments on the MNIST and CelebA datasets show that our method produces diverse and realistic inpaintings. Further, our model also estimates the likelihood of each sample which we show correlates well with the realism of the generated inpaintings.
