Ohajiki counter

This is an app for counting two colors of “ohajiki” (Japanese playing pieces). It is mainly designed for elementary school students and is typically used for counting up to several dozen pieces. However, according to the app’s specifications, it can handle counting up to about 2,000–3,000 pieces. Currently, it supports only two colors: brown and blue. How to Use Select an image. Use Auto White Balance or Color Temp. Switch to “Draw ROI” mode to select target areas (Multiple ROIs supported). Adjust Sensitivity and Ohajiki Size. Tap RUN ANALYSIS. Match the orange preview circle with the average nucleus. Increase ignore area if the app counts too much background noise. Disclaimer: For research and educational use only.
