Light enters the eye through the cornea, a transparent, dome-shaped surface covering the surface of the eyeball that helps to direct and focus incoming light. This light is then channeled toward the pupil, an adjustable opening whose size is controlled by the iris. The iris, a pigmented muscle, regulates the amount of light entering the eye by contracting or dilating the pupil, thereby ensuring optimal light levels for clear vision.
Once through the pupil, the light passes through the lens, a...

  • Proposed GTNet network to address channel narrowing and improve classification.
  • Developed dpFPN-Netv2 algorithm combining DPFM+RFM fusion for superior performance.

Main Results:

  • The dpFPN-Netv2 algorithm demonstrated higher target detection accuracy than RetinaNet-50.
  • Detection time for dpFPN-Netv2 was 52ms, significantly faster than RetinaNet-50's 90ms.
  • The improved MWI-DenseNet (GTNet) showed reduced computation and improved recognition accuracy.

Conclusions:

  • The proposed dpFPN-Netv2 algorithm significantly improves commodity image detection accuracy and speed.
