How to calculate the metrics [email protected], [email protected], ROUGE and METEOR score in table 7, 8, 9? #32
Comments

I wrote a function for calculating the metrics of table 8, and it looks good. def evaluation_metrics(data_path):
base = []
with open(data_path, "r") as fp:
lines = fp.readlines()
for line in lines:
base.append(json.loads(line))
correct = 0
incorrect = 0
comp_correct = 0
comp_incorrect = 0
pre_correct = 0
pre_incorrect = 0
ru_correct = 0
ru_incorrect = 0
for answers in tqdm(base):
gt = answers["gt"].lower()
type_ = answers["type"]
answer = answers["answer"].replace(" ", "").lower().replace(".", "")
if gt == answer:
correct = correct + 1
if type_ == "comp":
comp_correct = comp_correct + 1
if type_ == "presence":
pre_correct = pre_correct + 1
if type_ == "rural_urban":
ru_correct = ru_correct + 1
else:
incorrect = incorrect + 1
if type_ == "comp":
comp_incorrect = comp_incorrect + 1
if type_ == "presence":
pre_incorrect = pre_incorrect + 1
if type_ == "rural_urban":
ru_incorrect = ru_incorrect + 1
print("presence_correct:", pre_correct)
print("presence_incorrect:", pre_incorrect)
print("presence_Total:", pre_correct + pre_incorrect)
print("presence_Acc:", (pre_correct / (pre_correct + pre_incorrect)))
print("-" * 100)
print("comparison_correct:", comp_correct)
print("comparison_incorrect:", comp_incorrect)
print("comparison_Total:", comp_correct + comp_incorrect)
print("comparison_Acc:", (comp_correct / (comp_correct + comp_incorrect)))
print("-" * 100)
if ru_correct + ru_incorrect != 0:
print("rural_urban_correct:", ru_correct)
print("rural_urban_incorrect:", ru_incorrect)
print("rural_urban_Total:", ru_correct + ru_incorrect)
print("rural_urban_Acc:", (ru_correct / (ru_correct + ru_incorrect)))
print("-" * 100)
print("total_correct:", correct)
print("total_incorrect:", incorrect)
print("total_Total:", correct + incorrect)
print("total_Acc:", correct / (correct + incorrect))I am also waiting for the metric calculation function of Table 7 and Table 9. |
I am currently facing this issue. Have you implemented the metric calculations in other tables? |

I wrote a script for visual grounding evaluation in table 7. I used a bounding box calculate package [BboxToolkit] I think it's correct but I can't get the same result in paper. I don't know what's wrong. The def bbox_and_angle_to_polygon(x1, y1, x2, y2, a):
# 计算中心点坐标
x_ctr = (x1 + x2) / 2
y_ctr = (y1 + y2) / 2
# 计算宽度和高度
w = abs(x2 - x1)
h = abs(y2 - y1)
# 计算角度（弧度）
angle_rad = math.radians(a)
# 计算旋转后的四个角点坐标
cos_a = math.cos(angle_rad)
sin_a = math.sin(angle_rad)
x1_rot = cos_a * (-w / 2) - sin_a * (-h / 2) + x_ctr
y1_rot = sin_a * (-w / 2) + cos_a * (-h / 2) + y_ctr
x2_rot = cos_a * (w / 2) - sin_a * (-h / 2) + x_ctr
y2_rot = sin_a * (w / 2) + cos_a * (-h / 2) + y_ctr
x3_rot = cos_a * (w / 2) - sin_a * (h / 2) + x_ctr
y3_rot = sin_a * (w / 2) + cos_a * (h / 2) + y_ctr
x4_rot = cos_a * (-w / 2) - sin_a * (h / 2) + x_ctr
y4_rot = sin_a * (-w / 2) + cos_a * (h / 2) + y_ctr
# 返回多边形坐标
polygon_coords = np.array((x1_rot, y1_rot, x2_rot, y2_rot, x3_rot, y3_rot, x4_rot, y4_rot))
return polygon_coords
# read the answer file output by `GeoChat/geochat/eval/batch_geochat_referring.py`, and save as a list `geochat_predict`.
for i, predict in tqdm(enumerate(geochat_predict)):
answer = predict['answer']
answer = answer.replace("<unk>","").replace(" ","").strip()
images_dir = '../Dataset/GeoChat/referring_images'
image_path = os.path.join(images_dir, predict['image_id'] + '.png')
image = Image.open(image_path)
width, height = image.size
size_type = predict['type']
gt_bboxes = predict['ground_truth'] # list
predict_boxes = extract_bboxes(answer) # list
for i in range(len(gt_bboxes)):
# convert coordinates to float
poly = np.array(gt_bboxes[i]).astype(np.float32).reshape(-1) # [4,2]
gt_obb = bt.poly2obb(poly).reshape(1,5) # convert to [cx, cy, w, h, theta]
try:
pred_bbox = predict_boxes[i]
pred_bbox[0] = pred_bbox[0] / scale * width
pred_bbox[1] = pred_bbox[1] / scale * height
pred_bbox[2] = pred_bbox[2] / scale * width
pred_bbox[3] = pred_bbox[3] / scale * height
pred_poly = bbox_and_angle_to_polygon(*pred_bbox)
pred_obb = bt.poly2obb(pred_poly).reshape(1,5) # convert to [cx, cy, w, h, theta]
iou_score = bt.geometry.bbox_overlaps(pred_obb, gt_obb)[0][0] # calcualte obb Iou by BboxToolkit.
if iou_score >= 0.5:
correct += 1
except:
continue
dataset = 'GeoChat Bench referring'
print(f"Evaluating {dataset} ...")
print(f'Precision @ 0.5: {correct / total_cnt} \n')
Finally, I got a [email protected]=0.22744 as a result, my test data was come from GeoChat Bench referring.jsonl, with 7593 test samples. I was confused with the Iou result presented in the paper. I don't know how to get the same result. |

How to implement the function of extract_bboxes? |
I implement the import re
def extract_bboxes(output):
"""
Extract bounding box coordinates from the given string using regular expressions.
:param output: String containing bounding box coordinates in the format {<bx_left><by_top><bx_right><by_bottom>|θ}
:return: List of bounding boxes, each in the format [bx_left, by_top, bx_right, by_bottom, θ]
"""
# 修改正则表达式，确保最后一个数字和管道符号能够正确匹配
pattern = r'{<(\d+)><(\d+)><(\d+)><(\d+)>|<(\d+)>}'
matches = re.findall(pattern, output)
bboxes = []
for match in matches:
# 将所有匹配的坐标转换为浮点数，并添加到 bboxes 列表中
bbox = [int(coord) for coord in match] # 用int而不是float, 坐标是整数
bboxes.append(bbox)
return bboxes |

Hi author,
It is nice work.
When run the evaluation codes, I find the output is json file.
My questions: How to calculate the metrics in table 7, 8, 9?
Would you like to provide the code for computing the metrics?
Thank you
