【事件图像】RGB Image conversion to event Image

前言

        有些时候我们需要使用事件图像来做实验，但是事件图像数据实在是太少了，冲浪几乎得不到想要的数据，我们不得不使用正常的图像转换为事件图像来保证数据来源。

论文链接http://file///C:/Users/86137/Documents/temp/Gehrig_Video_to_Events_Recycling_Video_Datasets_for_Event_Cameras_CVPR_2020_paper.pdf        This repository contains code that implements video to events conversion as described in Gehrig et al. CVPR'20 and the used dataset. The paper can be found here

代码Code:

def RGB_to_EventImg(im):
    gray_img=cv2.cvtColor(im,cv2.COLOR_BGR2GRAY)
    # 偏移方向 建议设置区间[-5,5]
    xshift = 3
    yshift = -3
    xlong = gray_img.shape[1]-2*abs(xshift)
    ylong = gray_img.shape[0]-2*abs(yshift)
    pic_shape = [ylong,xlong,3]
    img = np.full(pic_shape, 0, dtype=np.uint8)
    # 如果图像相素偏移量>10那么记录该像素点
    for i in range(abs(yshift),ylong):
        for j in range(abs(xshift),xlong):
            if int(gray_img[i+yshift][j+xshift])-int(gray_img[i][j])>10:
                img[i][j]=[0,255,0]
            if int(gray_img[i+yshift][j+xshift])-int(gray_img[i][j])<-10:
                img[i][j]=[0,0,255]
    return img

if __name__ == '__main__':
    img = cv2.imread('test.png')
    cv2.imshow('frame', RGB_toEventImg(img))
    cv2.waitKey(0)
