Please try this

 if ( (mouseX >= imageX) && (mouseX < imageX+image.getWidth(this)) && (mouseY >= imageY) && (mouseY < imageY+image.getHeight(this)) )
         {
            int alpha = (image.getRGB(mouseX-imageX, mouseY-imageY) >> 24) & 0xff; 					
            if (alpha == 0) { result = false; } 
            else {result = true; }
         }
