Deep learning models have been very successful in computer vision and image
processing applications. Since its inception, Many top-performing methods for
image segmentation are based on deep CNN models. However, deep CNN models fail
to integrate global and local context alongside visual features despite having
complex multi-layer architectures. We propose a novel three-layered deep
learning model that assiminlate or learns independently global and local
contextual information alongside visual features. The novelty of the proposed
model is that One-vs-All binary class-based learners are introduced to learn
Genetic Algorithm (GA) optimized features in the visual layer, followed by the
contextual layer that learns global and local contexts of an image, and finally
the third layer integrates all the information optimally to obtain the final
class label. Stanford Background and CamVid benchmark image parsing datasets
were used for our model evaluation, and our model shows promising results. The
empirical analysis reveals that optimized visual features with global and local
contextual information play a significant role to improve accuracy and produce
stable predictions comparable to state-of-the-art deep CNN models.

本研究提出了一种新型的三层深度学习模型，通过引入一对多二元类别学习器，学习遗传算法优化的特征，并同时学习全局和局部上下文信息，从而优化整个模型以在图像分割方面取得有希望的结果。
