Parallel Processing

Parallel Processing

The brain processes sensory information rapidly due to parallel processing, which involves sending data across multiple neural pathways at the same time. This method allows the brain to manage various sensory qualities, such as shapes, colors, movements, and locations, all concurrently. For instance, when observing a forest landscape, the brain simultaneously processes the movement of leaves, the shapes of trees, the depth between them, and the various shades of green. This enables a quick and...

Vision

Vision

Vision is the result of light being detected and transduced into neural signals by the retina of the eye. This information is then further analyzed and interpreted by the brain. First, light enters the front of the eye and is focused by the cornea and lens onto the retina—a thin sheet of neural tissue lining the back of the eye. Because of refraction through the convex lens of the eye, images are projected onto the retina upside-down and reversed.

Compared the performance of CNNs, LSTMs, and the modified LRCN for road situation recognition.
Utilized data augmentation to balance the dataset and increase video file volume.

Main Results:

The modified LRCN model achieved 91% accuracy in detecting and recognizing multi-directional road contexts.
This represents a significant improvement compared to models using only CNNs or LSTMs.
Data augmentation played a key role in enhancing the model's performance.
