RASP: Revisiting 3D Anamorphic Art for Shadow-Guided Packing of Irregular Objects

Inspired by 3D anamorphic art—where seemingly arbitrary 3D objects align to form a coherent structure when observed from a specific direction—we propose a novel differentiable rendering-based approach to optimizing the packing of arbitrarily shaped objects by analyzing the shadows they cast when illuminated from different angles. Furthermore, we have utilized this method to reconstruct broken objects and generate multi-view anamorphic art.

L3D-Pose: Lifting Pose for 3D Avatars from a Single Camera in the Wild

3D pose estimation helps analyze animal movements but is limited by the difficulty of creating datasets. We address this with a hybrid approach using rigged avatars to generate synthetic 3D data. Our lightweight attention-based MLP converts 2D poses to 3D and retargets wild movements onto 3D avatars.

ScribGen: Generating Scribble Art Through Metaheuristics

While many methods bridge sketches and images, few turn images into expressive scribbles. Our work explores this untapped potential using metaheuristics instead of traditional learning-based approaches. By analyzing various algorithms, we show they strike a unique balance between creativity and efficiency.

Modified Harris Hawk Optimization Algorithm for Multi-level Image Thresholding

The article introduces a Modified Harris Hawks Optimization (HHO) Algorithm designed to enhance thresholding in grayscale images. Inspired by the hunting strategies of Harris Hawks, the original HHO algorithm has proven effective in solving diverse optimization problems. Building on this foundation, the proposed modifications aim to improve its adaptability and overall performance.

CameraSHOT

CameraSHOT is a simple yet powerful application that automatically analyzes an image’s theme or color scheme and seamlessly alters it with minimal user input. Inspired by Windows’ adaptive theme feature, which picks accent colors from desktop backgrounds, CameraSHOT goes a step further by reimagining the image’s existing color palette for a fresh look.

Multilevel Image Segmentation Using Modified Red Deer Algorithm

This paper introduces a Modified Red Deer Algorithm (MRDA) using an evolution strategy to optimize segmentation for grayscale images. Inspired by the behavior of red deer during their breeding season, the original Red Deer Algorithm (RDA) is a well-known meta-heuristic for solving complex optimization problems.
