对上述代码进行如下修改，是否改变基本功能：tatic int process(int8_t* input, int point_cnt, int height, int width, int stride, std::vector<float>& boxes, std::vector<float>& objProbs, std::vector<int>& classId, float threshold, int32_t zp, float scale) { int validCount = 0; float thres = unsigmoid(threshold); int8_t thres_i8 = qnt_f32_to_affine(thres, zp, scale); for (int a = 0; a < point_cnt; a++){ int8_t maxClassProbs = 0; int maxClassId = 0; for (int k = 1; k < OBJ_CLASS_NUM; ++k) { int8_t prob = input[(3+k) * point_cnt + a]; if (prob > maxClassProbs) { maxClassId = k; maxClassProbs = prob; } } if (maxClassProbs >= thres_i8) { int8_t rx = input[0 * point_cnt + a]; int8_t ry = input[1 * point_cnt + a]; int8_t rw = input[2 * point_cnt + a]; int8_t rh = input[3 * point_cnt + a]; float box_x = sigmoid(deqnt_affine_to_f32(rx, zp, scale)) * 2.0 - 0.5; float box_y = sigmoid(deqnt_affine_to_f32(ry, zp, scale)) * 2.0 - 0.5; float box_w = sigmoid(deqnt_affine_to_f32(rw, zp, scale)) * 2.0; float box_h = sigmoid(deqnt_affine_to_f32(rh, zp, scale)) * 2.0; objProbs.push_back(sigmoid(deqnt_affine_to_f32(maxClassProbs, zp, scale))); classId.push_back(maxClassId); validCount++; boxes.push_back(box_x); boxes.push_back(box_y); boxes.push_back(box_w); boxes.push_back(box_h); } } return validCount; } int post_process(int8_t* input0, int model_in_h, int model_in_w, float conf_threshold, float nms_threshold, float scale_w, float scale_h, std::vector<int32_t>& qnt_zps, std::vector<float>& qnt_scales, detect_result_group_t* group) { static int init = -1; if (init == -1) { int ret = 0; ret = loadLabelName(LABEL_NALE_TXT_PATH, labels); if (ret < 0) { return -1; } init = 0; } memset(group, 0, sizeof(detect_result_group_t)); std::vector<float> filterBoxes; std::vector<float> objProbs; std::vector<int> classId; // stride 6 int stride0 = 4 + OBJ_CLASS_NUM; int point_cnt = 8400; int validCount0 = 0; validCount0 = process(input0, point_cnt, model_in_h, model_in_w, stride0, filterBoxes, objProbs, classId, conf_threshold, qnt_zps[0], qnt_scales[0]); int validCount = validCount0; // no object detect if (validCount <= 0) { return 0; } std::vector<int> indexArray; for (int i = 0; i < validCount; ++i) { indexArray.push_back(i); } quick_sort_indice_inverse(objProbs, 0, validCount - 1, indexArray); std::set<int> class_set(std::begin(classId), std::end(classId)); for (auto c : class_set) { nms(validCount, filterBoxes, classId, indexArray, c, nms_threshold); } int last_count = 0; group->count = 0; /* box valid detect target */ for (int i = 0; i < validCount; ++i) { if (indexArray[i] == -1 || last_count >= OBJ_NUMB_MAX_SIZE) { continue; } int n = indexArray[i]; float x1 = filterBoxes[n * 4 + 0]; float y1 = filterBoxes[n * 4 + 1]; float x2 = x1 + filterBoxes[n * 4 + 2]; float y2 = y1 + filterBoxes[n * 4 + 3]; int id = classId[n]; float obj_conf = objProbs[i]; group->results[last_count].box.left = (int)(clamp(x1, 0, model_in_w) / scale_w); group->results[last_count].box.top = (int)(clamp(y1, 0, model_in_h) / scale_h); group->results[last_count].box.right = (int)(clamp(x2, 0, model_in_w) / scale_w); group->results[last_count].box.bottom = (int)(clamp(y2, 0, model_in_h) / scale_h); group->results[last_count].prop = obj_conf; char* label = labels[id]; strncpy(group->results[last_count].name, label, OBJ_NAME_MAX_SIZE); // printf("result %2d: (%4d, %4d, %4d, %4d), %s\n", i, group->results[last_count].box.left, // group->results[last_count].box.top, // group->results[last_count].box.right, group->results[last_count].box.bottom, label); last_count++; } group->count = last_count; return 0; }

对于第一个修改的代码块 `static int process(int8_t* input, int point_cnt, int height, int width, int stride,
std::vector<float>& boxes, std::vector<float>& objProbs, std::vector<int>& classId, float threshold,
int32_t zp, float scale)`，基本功能并没有改变。该函数仍然实现了目标检测的后处理，根据输入的 int8_t 类型指针和相关参数，提取有效的目标检测结果，并将检测框的位置、大小、目标置信度和类别编号存储在相应的向量中。

第二个修改的代码块 `int post_process(int8_t* input0, int model_in_h, int model_in_w, float conf_threshold,
float nms_threshold, float scale_w, float scale_h, std::vector<int32_t>& qnt_zps,
std::vector<float>& qnt_scales, detect_result_group_t* group)`，基本功能也没有改变。该函数仍然实现了目标检测的后处理，根据输入的特征图和相关参数，提取有效的目标检测结果，并将检测框的位置、大小、目标置信度和类别信息存储在 `detect_result_group_t` 结构体中。

两个修改的代码块主要对输入参数进行了调整，其中 `point_cnt` 表示检测点的数量，通过调整 `stride0` 的计算方式来确定。这些修改可能是为了适应不同的检测模型或数据集，但并没有改变基本的目标检测后处理逻辑。
