Alta – Rapid Test Reader


KEMENKES RI AKL 20304122347

New and Improved!

The new and improved RTR-1 uses an image processing method. During measurement, the lateral flow device is captured using a 5-mega pixel camera and the picture is analyzed using image processing algorithms for identification of either presence or absence of test line bands or test line band intensity levels. The reader converts the image into a grayscale and then classifies the intensity levels of the image in 0 to 255 grayscale range. The image processing algorithm undergoes various levels of filtering and segmentation to yield the correct intensity levels from the picture. Based on the preconfigured intensity levels, the reader classifies the band intensity and reads out the results as either positive or negative.
