Совмещение инфракрасных и телевизионных изображений при медицинской диагностике

Совмещение инфракрасных и телевизионных изображений при медицинской диагностике

Abstract

The authors propose a method of combining images obtained from sensors operating in different frequency ranges. Initially, the total luminous flux is split into two streams. From the first stream an image in the visible range is formed, and from the second one an infrared image is produced. Then, the pixels of both images are alternately stored in shared memory image. The order of entries is reduced to alternating lines of the image. For example, the odd-numbered lines correspond to the pixels of infrared images, and even ones to video image. Next, a reciprocal exchange of the parts of the opposite vertical neighboring pixels occurs. For this purpose, each pixel is divided into three parts. One part of the pixel is in its place, the other two equal parts are separately added to the adjacent vertical image pixels. Through calculations it is proved that the proposed method of combining images increases the information content of the generated image with respect to the original image up to six times.

От датчиков, работающих в различных частотных диапазонах. Первоначально общий световой поток разделяется на два: из первого формируется изображение видимого диапазона, из второго инфракрасного. Затем пикселы обоих изображений попеременно записываются в память общего изображения. Порядок записи сводится к чередованию строк изображений: нечетным строкам соответствуют пикселы инфракрасного изображения, а четным телевизионного. Далее организуется взаимный обмен частей противоположных по вертикали соседних пикселов. Для этого каждый из них делится на три части. Одна часть пиксела остается на своем месте, две другие равные части раздельно суммируются с соседними по вертикали пикселами. Расчетным путем показано, что предлагаемый способ совмещения изображений увеличивает информативность сформированного изображения относительно исходных в шесть раз.
