Pixel-wise Ear Detection with Convolutional Encoder-Decoder Networks [PDF]
arXiv, 2017 Object detection and segmentation represents the basis for many tasks in computer and machine vision. In biometric recognition systems the detection of the region-of-interest (ROI) is one of the most crucial steps in the overall processing pipeline, significantly impacting the performance of the entire recognition system.

Ear Identification by Fusion of Segmented Slice Regions using Invariant Features: An Experimental Manifold with Dual Fusion Approach [PDF]
arXiv, 2010 This paper proposes a robust ear identification system which is developed by fusing SIFT features of color segmented slice regions of an ear. The proposed ear identification method makes use of Gaussian mixture model (GMM) to build ear model with mixture of Gaussian using vector quantization algorithm and K-L divergence is applied to the GMM framework ...

Radiotherapy Induced Middle Ear Morbidities in Head and Neck Cancer Patients
Bengal Journal of Otolaryngology and Head Neck Surgery, 2021 Introduction Although post radiotherapy (RT) otological complications are complex and common, there is lack of data on its severity and spectrum. We intend to assess the incidence and severity of such ototoxicities in head neck cancer (HNCA) patients.

An Average of the Human Ear Canal: Recovering Acoustical Properties via Shape Analysis [PDF]
arXiv, 2018 Humans are highly dependent on the ability to process audio in order to interact through conversation and navigate from sound. For this, the shape of the ear acts as a mechanical audio filter. The anatomy of the outer human ear canal to approximately 15-20 mm beyond the Tragus is well described because of its importance for customized hearing aid ...

Deep Learning Approach for Ear Recognition and Longitudinal Evaluation in Children [PDF]
arXivEar recognition as a biometric modality is becoming increasingly popular, with promising broader application areas. While current applications involve adults, one of the challenges in ear recognition for children is the rapid structural changes in the ear as they age. This work introduces a foundational longitudinal dataset collected from children aged
