Increment per File

Below is some of my code. I am going through a folder, pulling every image, and finding the RGB value of every pixel, and determining which ones are blue. I am trying to only increment per file, but for some reason, it is continuing and adding every file's increment. 

try {
                int width = image.getWidth();
                int height = image.getHeight();

                for(int k = 0; k < height; k++){

                    for(int j = 0; j < width; j++){

                        Color c = new Color(image.getRGB(j, k));

                        int redVal = c.getRed();
                        int greenVal = c.getGreen();
                        int blueVal = c.getBlue();
                        //24 42 72

                        if ((redVal >= 0) && (redVal <= 80)) {
                            if ((greenVal >= 40) && (greenVal <= 105)) {
                                if ((blueVal >= 80) && (blueVal <= 135)) {
                                    count++;
                                }
                            }
                        }

                    }
                }

                System.out.print(count +" pixels are \"blue\", ");

Output:

23700 pixels are "blue"
27199 pixels are "blue"
38136 pixels are "blue"
40834 pixels are "blue"
41443 pixels are "blue"
50349 pixels are "blue"

How can I fix this? Thank you.

If you want count to only represent the blue in a single file, then reset it's value to 0 before iterating over the pixels:

int width = image.getWidth();
int height = image.getHeight();
count = 0;
...
