Description

None of images were identified from the ByteTrack paper: https://arxiv.org/pdf/2110.06864

Expected Output

Expect placeholders like these to show up in the parsed text:

markdown
![](img_p2_1.png)

#### (a) detection boxes

![](img_p2_2.png)

#### (b) tracklets by associating high score detection boxes

![](img_p2_3.png)

#### (c) tracklets by associating every detection box

Figure 2. Examples of our method which associates every detection box. (a) shows all the detection boxes with their scores. (b) shows the tracklets obtained by previous methods which associates detection boxes whose scores are higher than a threshold, i.e. 0.5. The same box color represents the same identity. (c) shows the tracklets obtained by our method. The dashed boxes represent the predicted box of the previous tracklets using Kalman Filter. The two low score detection boxes are correctly matched to the previous tracklets based on the large IoU.

Actual Output

Page 2 markdown output as an example:

markdown

| Frame t1 | Frame t2 | Frame t3 |
|---|---|---|
| 0.9 | 0.9 | 0.9 |

**0.1 0.1 0.1 0.8 0.9 0.4 0.8 0.1 0.8**

#### (a) detection boxes

#### (b) tracklets by associating high score detection boxes

**0.4 0.1**

#### (c) tracklets by associating every detection box

Figure 2. Examples of our method which associates every detection box. (a) shows all the detection boxes with their scores. (b) shows the tracklets obtained by previous methods which associates detection boxes whose scores are higher than a threshold, i.e. 0.5. The same box color represents the same identity. (c) shows the tracklets obtained by our method. The dashed boxes represent the predicted box of the previous tracklets using Kalman Filter.

Command Used

bash
const base = "https://esm.sh/@llamaindex/[email protected]";
const liteparse = await import(base);

await liteparse.default(`${base}/liteparse_wasm_bg.wasm`);

parser = new liteparse.LiteParse({
  ocrEnabled: false,
  outputFormat: "markdown",
});

const rawResult = await parser.parse(bytes);
console.log(rawResult);

LiteParse Version

2.13.1

Operating System

Linux

Additional Context

I have tested for other PDFs where the image placeholders do appear, which rules out issues in my configuration. I suspect the parser fails at this specific pdf.
