SEDNet: Shallow Encoder-Decoder Network for Brain Tumor Segmentation

1 code implementation24 Jan 2024 Chollette C. Olisah

Despite the advancement in computational modeling towards brain tumor segmentation, of which several models have been developed, it is evident from the computational complexity of existing models which are still at an all-time high, that performance and efficiency under clinical application scenarios are limited.

Consensus-Threshold Criterion for Offline Signature Verification using Convolutional Neural Network Learned Representations

no code implementations5 Jan 2024 Paul Brimoh, Chollette C. Olisah

This presents a challenge which puts a genuine signer at risk of being denied access, while a forge signer is granted access.

Understanding Unconventional Preprocessors in Deep Convolutional Neural Networks for Face Identification

no code implementations27 Mar 2019 Chollette C. Olisah, Lyndon Smith

Others are termed the unconventional preprocessors, they are: color space converters; HSV, CIE L*a*b* and YCBCR, grey-level resolution preprocessors; full-based and plane-based image quantization, illumination normalization and insensitive feature preprocessing using: histogram equalization (HE), local contrast normalization (LN) and complete face structural pattern (CFSP).
