一種影像中辨識物體的方法，係先拍攝一物體影像，再擷取該影像可辨識的特徵，並產生該抓取影像的X軸或Y軸長條統計圖，並經由X軸或Y軸長條統計圖中求出最小特定點及最大特點，經由最小特定點及最大特定點資訊，以多項式回歸分析計算出物體之形狀、大小及位置資訊；若判定物體為線性走向即可判斷為三角形；若為直線走向則判定為方行；若符合二次方程式則判斷為圓形。
A method for recognizing objects in images is disclosed. The method of the present invention comprises the following steps. First, acquire a digital image. Then, select one or more objects from the image according to a certain characteristic. Next, generate an x-axis histogram and/or a y-axis histogram from the segmented image. Then, find the zeroes and maxima for the x-axis histogram and/or the y-axis histogram and use the polynomial regression analysis to determine the shape, shape and location of each of the objects in the segmented image according to the zeroes and maxima. If the two curves linking two zeroes and one maximum in the x-axis histogram and the y-axis histogram are two sloped line, the corresponding object may be determined to be a triangle. If each of the four curves linking two zeroes and two maxima is a line, the corresponding object may be determined to be a rectangle.
