A first decoder obtains a region including an object targeted for recognition based on a feature map obtained by performing convolutional processing on a processing target image. Next, the first decoder obtains, from the feature map, a partial feature map of a portion corresponding to the obtained region including the object targeted for recognition. Then, a second decoder obtains pixels corresponding to the object targeted for recognition based on the partial feature map. This reduces the amount of calculation required for decoder units included in a neural network.

A refractive index modulation element made of a refractive index modulation material. The refractive index can be thermally modulated. The refractive index modulation material can be a silicone resin represented by the following formula R.sub.n SiO.sub.(4--n)/2,where the average value of n is 0.5 to 3 and where K is an aliphatic or aromatic group with 1 to 18 carbon atoms or other functional group. The silicone resin has a spectral transmission factor that on average is higher than 80%, within the wavelength range of 350 nm to 1,600 nm, and a refractive index temperature dependence of -0.001/.degree.C. to -0.00005/.degree.C.

Refractive index modulation device and method of refractive index

The invention is a method for the preparation of organic solvent-soluble polyheterosiloxanes containing MO.sub.2 (M=Ti or Zr) and SiO.sub.2 units. A compound MA.sub.4 (M=Ti or Zr, A=hydrolyzable group) and a compound Si(OR).sub.4 (R=hydrocarbon group or alkali metal atom) are hydrolyzed and condensed in the presence of a carboxylic acid, a phenol, or a diketone. This is followed by the addition of an organosilane R.sup.1.sub.3 SiX (R.sup.1 =hydrogen or hydrocarbon group, X=hydrolyzable group) and hydrolysis and condensation.
