Cufft problem on Jetson TX2i

[manhtb310]

Hi,
I recently implemented a extension of KCF tracking algorithm on Jetson TX2i based on your code.
At kcf.h file in src folder, I added 2 pointer arrays are: std::unique_ptrfilterPool[4] and std::unique_ptr multiFilters[(int)4] .
At kcf.cpp file, I also modified train function to use filterPool[4] array, the code like below:
When i = 3 in train function, the memory of filterPool[4] is overwrite

filterPool[0]->kf [13 x 25] 1ch = [ (1.6e+02,0), (0.46,-0.00033), (0.39,-0.00071), (0.15,-0.00056), (0.66,-0.00033), (0.34,0.00039), (0.042,4.4e-06), (0.045,-5.4e-05), (0.041,5.9e-06), (0.13,0.00022), … ]
filterPool[1]->kf [13 x 25] 1ch = [ (6.2e+02,0), (2,-0.0014), (1.7,-0.0017), (0.67,-0.0012), (2.9,-0.00045), (1.5,0.00076), (0.19,-6.9e-05), (0.2,-0.00022), (0.0086,0.00027), (0.039,0.00077), … ]
filterPool[2]->kf [13 x 25] 1ch = [ (5.9e+02,0), (2.1,-1.6e-06), (0.28,1.1e-06), (0.14,-1e-06), (0.06,7.3e-07), (0.081,0), (0.05,-2.7e-06), (0.026,8.2e-07), (0.023,2.8e-07), (0.018,1.1e-06), … ]
filterPool[3]->kf [13 x 25] 1ch = [ (0,0), (0,0), (0,0), (0,0), (0,0), (0,0), (0,0), (0,0), (0,0), (0,0), … ]
void KCF_Tracker::GaussianCorrelation::operator()(ComplexMat&, const ComplexMat&, const ComplexMat&, double, bool, const KCF_Tracker&, bool, bool)() {
void Fft::inverse(ComplexMat&, MatScales&)() {
complex_input [13 x 25] 1ch = [ (6.6e+03,0), (2.8e+03,0), (3.6e+02,0), (1.9e+02,0), (76,0), (1.1e+02,0), (65,0), (33,0), (29,0), (23,0), … ]
}
void Fft::forward(const MatScales&, ComplexMat&)() {
real_input 1 x 25 x 25 1ch = [ 1.1, 1, 1, 1, 1, 1, 1, 1, 1, 1, … ]
}
}
filterPool[0]->kf [13 x 25] 1ch = [ (0.32,0), (0.11,0), (0.073,0), (0.16,0), (0.26,0), (1.4,0), (3.3,0), (2.8,0), (1.4,0), (0.91,0), … ]
filterPool[1]->kf [13 x 25] 1ch = [ (0.36,0), (0.013,0), (0.14,0), (0.077,0), (1.1,0), (0.29,0), (0.9,0), (2.9,0), (2.9,0), (0.52,0), … ]
filterPool[2]->kf [13 x 25] 1ch = [ (0.33,0), (1.2,0), (0.71,0), (0.039,0), (0.35,0), (1.3e+02,0), (40,0), (1.8,0), (6.4,0), (9.1,0), … ]
filterPool[3]->kf [13 x 25] 1ch = [ (6.3e+02,0), (2.5,1.5e-07), (0.33,-8.8e-07), (0.17,-4.5e-07), (0.071,-2.8e-06), (0.097,0), (0.06,-7.1e-07), (0.031,-2.4e-08), (0.027,-8.7e-08), (0.021,-1.9e-07), … ]

Can anyone help me with this issue,
Thanks.

Please, make your extension and testing data public. Then describe, what is the purpose of the extension. Without that, it's difficult for me to help you.

Hi @wentasah ,I am trying to implement SCT Tracking [1] using cufft on Jetson TX2i. I just created a github repository and pushed extension code on it: https://github.com/manhtb310/kcf_extention.git
Testing data is Freeman1 folder, which also included on the github repository.
Many thanks for your help.
