S$^3$AD: Semi-supervised Small Apple Detection in Orchard Environments

no code implementations8 Nov 2023 Robert Johanson, Christian Wilms, Ole Johannsen, Simone Frintrop

However, crop detection, e. g., apple detection in orchard environments remains challenging due to a lack of large-scale datasets and the small relative size of the crops in the image.

High-Level Parallelism and Nested Features for Dynamic Inference Cost and Top-Down Attention

no code implementations9 Aug 2023 André Peter Kelm, Niels Hannemann, Bruno Heberle, Lucas Schmidt, Tim Rolff, Christian Wilms, Ehsan Yaghoubi, Simone Frintrop

Our proposed topology also comes with a built-in top-down attention mechanism, which allows processing to be directly influenced by either enhancing or inhibiting category-specific high-level features, drawing parallels to the selective attention mechanism observed in human cognition.

Segmenting Medical Instruments in Minimally Invasive Surgeries using AttentionMask

no code implementations21 Mar 2022 Christian Wilms, Alexander Michael Gerlach, Rüdiger Schmitz, Simone Frintrop

Our evaluation in an object proposal generation framework shows that our adapted AttentionMask system is robust to image degradations, generalizes well to unseen types of surgeries, and copes well with small instruments.

Localizing Small Apples in Complex Apple Orchard Environments

no code implementations23 Feb 2022 Christian Wilms, Robert Johanson, Simone Frintrop

Since the apples are very small objects in such scenarios, we tackle this problem by adapting the object proposal generation system AttentionMask that focuses on small objects.

DeepFH Segmentations for Superpixel-based Object Proposal Refinement

no code implementations7 Aug 2021 Christian Wilms, Simone Frintrop

Class-agnostic object proposal generation is an important first step in many object detection pipelines.

Superpixel-based Refinement for Object Proposal Generation

1 code implementation12 Jan 2021 Christian Wilms, Simone Frintrop

Precise segmentation of objects is an important problem in tasks like class-agnostic object proposal generation or instance segmentation.

AttentionMask: Attentive, Efficient Object Proposal Generation Focusing on Small Objects

1 code implementation21 Nov 2018 Christian Wilms, Simone Frintrop

We propose a novel approach for class-agnostic object proposal generation, which is efficient and especially well-suited to detect small objects.
