Transformar “máscara” em vídeo

[PH1005]

Boa tarde , me chamo Pedro Henrique, sou assinante da IA Expert (inclusive, gostaria de comentar que o curso é excelente), venho por meio deste fórum perguntar se alguém poderia me auxiliar com uma dúvida. No caso, estou tentando mesclar codificações das aulas de detecção de movimento e de rastreamento de objetos, utilizando python e openCV. Bom , minha dúvida é o seguinte, queria saber se é possível aplicar os parâmetros de shitomasi e lucas kanade em uma máscara retirada de um algoritmo de subtração de background, já estou tentando fazer essa junção, porém não consigo fazer com que o algoritmo shitomasi-kanade “leia” a máscara obtida como um vídeo.

cap = cv2.VideoCapture("result")

(sendo “result” a máscara do algoritmo de subtração)

Para um entendimento mais fácil da situação, estou enviando o código.

Olá Pedro!

Parabéns pela ideia do projeto, é bem interessante!

Pelo que entendi, a ideia é aplicar o algoritmo subtrator de fundo e depois usar o resultado para o algoritmo Optical Flow rastrear, seria isto?

Se sim, pelos fontes que você mandou, você estava chegando lá, só faltavam ajustar os parâmetros das imagens usadas entre os dois algoritmos.

Fiz uma implementação simples baseada nesta ideia, vou mandar na próxima resposta aqui. Provavelmente você terá que ajustar os parâmetros de cada algoritmo de acordo com seu projeto, pois deixei a parametrização padrão de cada um.

Olá Dalton, com o seu algoritmo consegui avançar um pouco, consigo até visualizar a tela preta com as linhas formadas, porém a janela trava e não consigo rodar o vídeo, acabei obtendo outro problema que foge do meu conhecimento, normalmente eu pesquiso mas não entendi oque realmente é esse erro. No caso o erro é o seguinte:

Desculpe ficar pedindo ajuda, mas se puder me auxiliar, ficarei muito agradecido.

[Dalton Vargas]

Pedro,

poderia compartilhar o fonte completo? Assim consigo analisar e testar aqui também.

Ah e quando for mandar o fonte, por favor não esqueça de mandar em uma mensagem separada, adicionando como bloco de código, assim o script não perde a formatação original.

Olá Dalton, vi seu vídeo e de fato está rodando, mas no meu vídeo teste eu não consigo rodar esse código, fico com o mesmo erro que mandei anteriormente. Vou mandar meu vídeo para ver se você consegue encontrar o problema, o algoritmo é o mesmo que você mandou.

https://drive.google.com/file/d/1WXv7sMaxNtVae3rQkQfoc4gn7amuIFGR/view?usp=sharing

Ah, e a linha que eu passo as variáveis para inteiros foi só uma passagem porque anteriormente estava dando erro também, acho que para o vídeo que estou usando existem alguns problemas e não tô sabendo resolver. Vou mandar o Erro de novo também.

Olá Pedro!

Fiz o teste aplicando somente o Optical Flow e parece que devido aos insetos estarem desfocados desde o início do vídeo, o algoritmo não consegue indetificar os contornos/arestas. Já nos objetos que estão mais nítidos (marca da câmera, tempo de vídeo, camisa branca ao fundo) ele consegue identificar. Segue o vídeo .

Minha sugestão seria gravar um vídeo mais focado nos insetos (se estes forem o objetivo).

Também se puder compartilhar a ideia do projeto, assim podemos pensar em mais soluções. Caso não queira compartilhar aqui no fórum, pode mandar no meu e-mail: daltonluizvargas@hotmail.com
