Due to effects of the light by water and other particles, the quality of underwater image will degrade. The traditional underwater image segmentation methods based on intensity and spectrum have difficulty in determining boundary. Inspired by the visual system of mantis shrimps, this paper constructed a feedback neural network model, in which the parameters were optimized using machine learning method. Based on this model, we combine the polarization and intensity information to achieve the underwater polarization image segmentation. The results of experiment prove that the neural network model designed in this paper can improve the accuracy of underwater image segmentation.

“…Sizes of ommatidia and skewing both change with the sizes of the animal. When the animal grows, the pattern of skewing changes and adapts the eye to the lengths of the extended raptorial appendices Di Stefano et al 1990). These last subserve the high-speed strike for hitting a prey (Caldwell & Dingle 1976).…”

Morphology of adaptation and morphogenesis in stomatopod eyes

Ommatidia of eyes of stomatopods change with adaptation to light or dark. With dark adaptation the crystalline cones shorten and the retina becomes longer. This is due to contractions of myofibrils in veils surrounding the cones, while microtubules within the accessory pigment cells maintain the cytoarchitecture of the ommatidia. Here we describe the changes in Lysiosquillina maculata, a stomatopod living in an extremely bright habitat, which is compared to stomatopods from other ambient light conditions. The postlarval eye of stomatopods grows over the larval eye, gradually substituting it. Growth starts from a morphogenetic furrow at the inner border with the stalk. Similarly, in the adult eye as well at the inner margin between the stalk and the cornea, a morphogenetic furrow is inserted, which at its interior contains a proliferation tissue with clusters of developing ommatidia. At its distal side the proliferation tissue appears to generate the dioptric apparatus, i.e. veils, corneagenous cells and cones, and at its more proximal part the basement membrane, accessory pigment cells and retinular cells. The ommatidial components grow at different speeds.

Abstract.Hairs on the abdomen of honeybees contain dendrites and a rod and ring structure composed of black particles, presumed to be superparamagnetic (SPM) magnetite. The rod and ring were divided into compartments and each compartment approximated by a dipole. The magnetic fields were calculated at a point P at various locations for a change of the external geomagnetic field from zero to 0.5 G in 0.1 s. The magnetite amplifies the external field at the rod/ring-dendrite interface. The induced electric field and potential difference for a small circular area are in the order of 10 -7 V/m and 10 -~3 V respectively. Mechanisms are proposed for amplifying the electric fields in the dendrite and in an integrating nerve fibre. A hypothesis is developed for associative learning of visual and magnetic stimuli. If magnetic and visual inputs are associated in the ganglion and in the brain, very small changes of either magnetic or visual inputs could be perceived. A bee could sequentially follow the images associated with magnetic gradients on a cloudy day and find the food source.
